Honestly I expect a fairly large amount of schedulers to appear, and the major distros to end up with their own scheduler flavors available. "Desktop" vs "Server" installs will actually make a difference in that regard more likely at a minimum.

The biggest set of experiments I expect to see are on the desktop; can you schedule based on knowledge of what the user can see and interact with, such that while overall system throughput is down, user-perceived responsiveness is up? Can you schedule such that a Steam game (which itself involves multiple processes) gets a lower maximum time per frame?

The Steam games part is already happening, as sched_ext is being evaluated (i.e., they have a scheduler already, with benchmarks results, etc) for the Steam Deck:
