I don't know where/if it's explicitly documented, but it would be with
apt if anywhere.

If some of the packages providing a virtual package are explicitly
installed, and some auto-installed, it could reasonably auto-remove the
latter group (though I don't think it does).  But if all of them are
auto-installed, which will be the case for kernel packages, it can't
tell which should be kept and which removed.

But nothing will auto-remove the wireguard package.  So you would have
to keep it as a transitional package for one release cycle, even when
it depends on just wireguard-tools.

Yes, this is annoyingly complicated.  That's why I need there to be a
plan.

Humour is the best antidote to reality.
