True, but the biggest problems are things like new versions of colord
that trip up a selinux-policy denial which then in turn cause
gnome-settings-daemon to crash which in turn gives you a failure at GDM.

None of that involves user data.

At least in GNOME we used to have a strong policy of enabling this, but
admittedly a lot of core applications do it wrong.

Yes - that we don't need to solve the user data problem for all software
immediately to support rolling back a Mesa upgrade.
