...sort of. It talks about the feature, but does not talk about the
syntax removal, which is what I was originally searching for in the
release notes.

I do tend agree with this intuitively but don't have any data to back it
up either way. That said, we did modify the command and it would be good
to at least mention the fact we dropped "FROM" somewhere in the release
notes. It provides a good reference in case someone reports an "issue"
in the future stemming from dropping the "FROM" keyword, we can say "oh
it changed in PG13, see XYZ."

(Speaking from having used the release notes to perform similar
troubleshooting).

Sure, and AIUI they're going to do that, mostly that was a reference
point to the changed syntax.
