I am not sure I am following you here, but people do run WM without a
compositor, it is a reality.

And GTK supports that, at least up until now, and that's fine by me.

But it's already the case, I am not advocating to reinvent the entire
ecosystem of UI interactions here, I am merely asking if a setting to
help GTK decide to go CSD or SSD instead of just detecting the
presence of the compositor alone would be interesting...
