I wonder why it isn't in sync a bit, but at the end of the day, it's a detail.
Also with any luck, you'll now get letter based miles credit.
Bolding is mine. It's not always a detail depending on your situation. Some examples where changing a marketing carrier is not a detail:
- for a FB Ultimate, a DL-coded flight is not eligible to UXP
- for a DL member US-based, I believe there could be some impact on passing from a DL-marketed flight to a AFKL one, but I have to say I am not familiar enough with SM rules to be 100% sure on this one
- if you have a corporate contract with AF, a DL-marketing may not be eligible to discount or annual rebate.
Just a few examples showing that a marketing carrier should never be changed without pax agreement IMHO.
