There may be compositors for very specific cases (e.g. Steam Deck) that handle resets very well, and those would like to be properly notified of all resets because that's how they get the best outcome, e.g. no corruption.

Agreed, in theory.<br>

In practice, from a user PoV, right now there's pretty much 0 chance of the user session surviving if the GPU context in certain critical processes (e.g. the Wayland compositor or Xwayland) hits a fatal reset.
