It's indeed not a "core" pattern any more, but just like with
specialforms-vs-macros, the difference between core patterns and built-in
patterns is just an internal implementation detail, and the way I read
the Texinfo doc, I don't see such a distinction: `rx` is (oddly) placed
together with `and` and `or`, which are both core patterns.

BTW, regarding the `grok/pcase` example, maybe the doc should make it
more clear that this example is a contrived piece of code intended to
combine as many of `pcase`s features as possible, and doesn't intend to
encourage using such style (which I personally find horrendous ;-).
