An important difference is also that it is not the canonical `pcase'
counterpart of something existing (as Stefan mentioned), which is why I
dropped the "pcase" suffix.

As we want to drop the "pcase" suffix in this case, shouldn't the name
tell that this is about matching?  Else, "all" is IMHO meaningless.
OTOH adding "all" to the name would be ok for me, since it's not obvious
how the clauses are logically combined.
