[fedora-arm] Re: Wiki claims RPi 4 is not supported

That is correct, there's a very large cavernous gap between "may work
for a number of purposes including yours" and something that will work
for the vast majority of users.

The core "supported" status will change when the standard GUI runs
fully accelerated and users have WiFi/sound and the things that are
associated with a reasonable desktop experience as that's the default
means a lot of new users expect. That's what I, as the RPi maintainer,
did when we introduced "supported" RPi3. Any less than that the
support queries are too high.

Those two are critical.

The Wiki page explicitly does not say "it does not work" it says it's
not supported. The words are chosen specifically. By saying it's
supported a user can rock up when something doesn't work and ask for
support or assistance, if something breaks we block the release etc.
By saying it's not supported a user may try it and if it works for
them great, but if it breaks while we'll attempt to fix it that may
take time and it may not get fixed.

Oh look, a user asking for "support".... see my points above!

It's one reason, but not the only ones.

Yes, and that's the idea, a more advanced user will be able to
ascertain it works, and it has for a *long* time and likely be able to
do most of what they want to do.

For a headless server it should be fine, but a general user comes via
Fedora Workstation and expect and accelerated desktop and sound and we
don't have them working ATM.
