ISTM the user facing docs refer to cluster as an "obsolete" variant /
spelling, rather than something marked as deprecated. This feels like
it is meant to imply that the old functionality is not planned for
removal in some future release (ie. deprecated), but that you may find
that certain bits of support for it are already removed/broken. If
that was the intention, I guess it gives justification to remove it
now; that said it does seem rather unfriendly to not give any kind of
bridge release to get from one side to the other, so I think the ideal
would be to keep it for v19 and remove it in v20.
