I sometimes help film live events for a friend when he needs extra hands. Getting the framing perfect is really hard unless you're very good with the camera. Panning to follow a moving subject while simultaneously making sure everything else in the shot is desired is... really hard. Imagine being able to simple film a "general area" in 8K and the post-production team could handle all the framing/panning and still get 1080 output. That would be an amazing feature of filming in higher resolution. So the higher the better... let's get there, and make everyone's life easier.

Not really. For one, 4K already makes life more difficult, adding huge trnascoded files, slow renders, proxy workflows, etc. That's on a pure technical level.
On an aesthetic level, it's a bad habbit too and cropping in post is a lazy copout or an emergency kludge. Setting your frame is more than just "getting what you want in the final output", it affects parallax, compression, etc. Croping from 2x the frame is not the same optically. And deciding in post means a less well thought out frame in the first place. So, it's nice as a emergency kludge to save ones ass, for documentary, ad work or news, but not so good for movies.
