State (in doc string and Elisp manual) that N in \N is not just "a
digit" but a digit from 1 through 9. Make clear that in "Nth
subexpression", N is one-based, not zero-based.

I don't think that makes any sense. The wording is:
`\N' means substitute what matched the Nth `\(...\)'.
If Nth parens didn't match, substitute nothing.
I can't see anybody interpreting Nth as having "zeroth" as a valid
meaning.

Most things in Emacs and Lisp in general are zero-based.
It is not obvious that this is one-based. And Oth and zeroth
make as much sense as 1th and oneth. If counting is zero-based
then the 0th element is exactly that: the entry that is indexed
by the number zero.

Let me put it differently: Is there a good reason NOT to say that
"N is a digit from 1 through 9"?
