We are in regression only mode even before -rc1 these days ? including
for code that is basically completely unused upstream (which is what
this is trying to fix) ? :-) That's rather full-on ...

Anyway no biggie, it will just slow down some getting some of the other
drivers I suppose, though we can always explicitly list the dependency
on this tag to work around it.
