Likely not, but with the config option present, downstreams that care
about a well-defined set of guest OSes could exhaustively test the
behavior of those guests, and if the change worked fine for all of the
OSes, they could just flip the config option in the downstream package
(rather than carrying a downstream patch).
It was just an idea anyway; if it's too late for the pending release, I
guess a more robust method could be devised, in time for the next release.
