I agree with Jani that for 0.18 this won't be possible. However, there
is probably no urgent reason to upgrade (given you know it will cause
you some problems) so the question is can we add some functionality to
cover this use case. Given the way we do the folder matching I think it
unlikely we would want to add globbing/wildcards to the start of a path
(*).

However, we might be able to support maildir++ as its own prefix. If you
could so searches of the form maildir++:.foo.bar.** which would match
the maildir .foo.bar and all submaildirs++ (eg .foo.bar.a.b etc) would
that be sufficient?

This wouldn't deal with 2013/.foo.bar but would allow .foo.bar.2013

Would this be enough help to make it worth considering?

Best wishes
