If we want to do that, we need to rewrite both the ELisp manual and
the doc string to never use these.  With the current text of the
manual, you simply cannot ignore them.  (Personally, I think trying to
stop using them is futile, since so many people who actively use
'pcase' use these terms freely in their messages and other text they
write.  But that's me.)

There are quite a few of these there.
