Has that name actually been formalized in any way? I still like it, but
last I heard it wasn't officially anything more than a misunderstanding
and a joke.

It seems unlikely that that "switch" will involve removing X entirely,
since many things will still rely on X, even if the X they rely on ends
up getting run nested inside of Wayland (as I believe is a supported
scenario, exactly for backwards-compatibility reasons).

As such, anything that relies on X should still be able to keep working,
as long as the existing X session continues running. It's just that
anything that relies on Wayland won't be able to work until the restart
is done.

- From my perspective, that's perfectly acceptable; everything that was
working before continues to work, but you don't get the new
functionality until you restart.

If that's *not* the case - if things that rely on X will break, or (more
likely) if some of the things which people use will be upgraded from
versions which rely on X to versions which rely on Wayland - then at the
very least a pre-upgrade warning should be provided, with the
opportunity to cancel / postpone the upgrade.

One of the things people have been asking for, when it comes to systemd,
is such a warning in the form of a debconf prompt; however, there seems
to be resistance to that idea, and indeed I'm not sure it hasn't been
outright rejected.
