It's reasonable to expect that such cases will become more common as the
extension community matures. It wasn't something we especially had to
worry about in the initial implementation of extensions, but it seems
totally worthwhile to me to add it now.
FWIW, I agree with using "CASCADE" to signal a request to create required
extension(s) automatically.
