Even if, that's irrelevant.
Actually that would make the solution *extremely* simple: have SDL1 tag the window as "_NET_WM_BYPASS_COMPOSITOR", "1" - problem solved.

You are aware that "override_redirect" just means: "Dear WM, please ignore me"?
Every popup and tooltip, many docks, some "fullscreen" windows of all sorts (often because they're just popups), a whole bunch of synthetic windows and whatnot are.
It's not somehow a hint on the content of the window or some SDL exclusive.
The state is not a usable hint on whether compositing should be used. You enter the field of heuristics what means you'll hit false positives for sure.

I think there's a misunderstanding about "regular" - i was only talking
about "override_redirect windows that are not interested in skipping the
redirection", NOT about "non override_redirects".

The problem is not that it's hard to do, the problem is that nobody does and especially you can not expect "legacy" clients to alter to match your reconsiderations about the protocol.
Providing the ability to hint this preference is fine, but an absent hint only indicates an absent hint - not any intention.
