In my case, it is not working that way - the problem is 100% repeatable
if I just dpkg --purge libgl1-mesa-dri

I am happy to test it in some other way to see if there is a reason why
the indirect GLX doesn't work, but I would need some suggestions what to
check.

That is correct - but according to popcon, 1 in 7 users of xserver-xorg
don't have the package xorg, so when they upgrade, they won't get the
dependency that way.
