That's not good and relates to my my long-held
thought that such compat options should be named for
the feature they change and not a specific version
(didn't mention it, since I don't use any compat options and
have had other issues more important for me).

But the way it is now -- if someone is using a compat option
for an earlier version, and now needs another compat option
for some other incompat, then they have a problem.  I'm
fairly sure that wasn't by design, as the compat options seem
to have been meant to solve specific compat problems that
people needed, as they came up -- not as a new, long-term
feature to control various compat issues.
