Actually, I think Breaks+Replaces is wrong here.

Breaks+Replaces allow for silent replacing of the old package, but here
you need to forcefully remove it, which is what you'd use Conflicts for.
As a data point, that what we usually use when renaming packages during
ABI breaks like what has been done for #916881.

Incidentally, I think that would also cover the just openend #918372,
as with a Conflicts the libgmsh3 package from testing woudln't be
installable, so it would force an upgrade to the version in unstable,
making the test pass.
