'xhost si:localuser:root' or blame other for not rewriting software
that is working for ages.

We don't really need a list of GUI processes that want to run as root.
We are aware such things exist. The point is that they're a bad idea
and always have been, and the switch from X to Wayland is an excellent
point at which to say "this is the point where we're not going to
enable this bad idea any more, and tell people to make better, more
robust, more secure software instead". If we never do that, we continue
to have bad, insecure software forever.

If you really need something that has to run as a GUI root process
right now, and none of the workarounds discussed earlier in the bug
works for you, by all means, switch back to X for now. There's a reason
we keep X as a prominent option in F25." -

This is not a 'weakness' of Wayland, it's a weakness of gparted (and
other graphical applications that try to run as root). gparted should
not run its UI as root. It should run its UI as a regular user and use
PolicyKit or something else similar to gain elevated privileges only
when necessary to query or modify devices.

Many graphical applications have already been written along these
lines. Doing it is not rocket science." -

Actually those introducing a new policy should provide all the apps
users do need. If it isn't rocket science they should provide those
apps. They can't expect that other projects obey. Due to this attitude
the Linux community lost a lot of excellent apps and never somebody
wrote replacements for those apps, when those excellent projects were
discontinued, because the people writing those apps in the first place
without getting money for it, don't have the time to rewrite their
projects again and again, each time a few fully paid developers and/or
spoilt children who don't have a life beyond their computer hobby
enforce something new.
