They've really expanded the scope, as noted in the article that's linked above, particularly with respect to new lounge space.

I was just thinking about this as was fighting the crowds through the F connector last night. It's going to be a very long and painful wait for project completion for SFO UA flyers.

One point to note, it's now possible to check bags (domestic flights only) at car rental center and long term parking if you're at least 90 minutes prior to departure. This is a big convenience compared to finding your way to the T3 UA check-in counters.
