The issue is NW ordered A320s with the CFM56-5A1s (~ half the fleet) and the others with CFM56-5A2s The 5A2s have able 2K more thrust than the 5A1 engine. While that not might seem like a lot, for SLC which is hot and high it is.
Why DL can't change the trust plug and make them all 5A1s is a great question I can't answer. As far as I know it can be done but I'm guess it might have something to do with the fact those engines are sent out of house for overhaul and the power-by-the-hour agreement NWA signed doesn't allow it. Of the CFM56-5A is different from the CFM56-5B and CFM56-7B engines.
Haven't seen many Domestic Flights referred to as "Payload Optimized" before. This is common on ultra long haul international (JNB, SYD, formerly DXB) and can be a reason why the flights commonly go out with seats to spare (can have a significant impact to Non-Revs). My guess is it was critical some out of the ordinary cargo was needed to be carried on this route.
'320's (and '319's) routinely fly TCON's on DL and other carriers and that's the way things are and will remain. The days of flying excess capacity are long gone.
Once in a great while, this will result in weight restrictions before loading and that's a bit of a hassle. Enroute, maybe a fuel diversion and a bit of a greater hassle.
But, that's better than losing a frequency which is the alternative.

I was on a new A319 from MSP-BZN that was payload optimized a couple of months ago. No cabin baggage could be checked, it all had to fit in the cabin. Weird given the relatively short distance.
Do the few added seats to the new A319/A320 configuration make this more commonplace?

(DL's A319s have the same issue as the 320, 23K is the highest thrust you can go on the CFM56-5A for the 319 motors (5A3 and 5A4) the CFM56-5B7, which is what AA has on the few nAAtive birds are 27K motors. That allows them to be at full MTOW package. Its basically like the 73W fleet at DL, pocket rockets.)
Sometimes. Sometimes it can be other issues. IIRC when the 764 did ATL-DKR-JNB it was always payload optimized but I think it had more to do with the 764 having a somewhat small window for the CG because the plane is so long.
DL uses the 737/757/767/777/320/330 for transcons. At one point on of the longer routes in the system (LAX-TPA) was a 320. Went 737 once AA showed up on the route. (and 2x daily at times)

Payload optimized
Boarding DL1745 SMF-MSP right now. Lots of announcements about being payload optimized and that they won't gate check any bags, all bags must fit in the cabin. If the bag is still going on the plane what difference does it make if it's in the cabin or gate checked?
Boarding is going to be a mess, as per the usual at least 2/3 of passengers appear to have a roller bag.
When all the bins fill, what will happen? Will they check the bags on a different routing, or start IDB-ing people?

I checked my bag at the counter and there was no mention of weight restriction or otherwise. App says my bag is on the plane.

A similar discussion from a few years ago:
Payload Optimization Flight
Some good post from Delta insiders.
I have heard it a few times on some relatively short flights (<1,000 miles). All depends on the winds, loads, cargo, etc.
The issue with gate checking is the way weights are calculated. Passenger + cabin baggage has a different weight calculation than passenger + checked baggage. Here is a news article with some details (recent average weight increases from 2005):

Could be Cargo, could be projected headwinds, or rough weather, or far more checked baggage than expected.
Look at the media baggage allowance, and with today being inauguration day it wouldn't be shocking to see some media people leaving California's capital possibly on the way to DC.
1ST AND 2ND BAG
ADDITIONAL BAGS
Domestic
Same as regular baggage allowance if no more than 50 lbs. (23 kg)/62 inches.
If overweight / oversize, flat media rate of 50 USD/CAD* applies.
3rd-25th bags 50 USD/CAD* each if no more than 100 lbs. (45 kg) and 115 total linear inches*

If anyone is going to the inauguration on this flight, then they'll miss the whole show, especially with a change at MSP! Anyone going to the event would have left yesterday at the latest! I'm not sure why you even mentioned that!

They may not be covering the inauguration itself as yes they would be too late, but there are tons of marches and protests to cover tomorrow.
