Thanks for the idea, but:

I'm not sure what that gains over just using pcre2_maketables() and
having the length available so you can overwrite the tables if you want
to. An alternative is to have pcre2_maketables2() which returns an extra
parameter, but I think this is such a rare requirement, so I didn't want
to add too much to the API.

That is a useful idea; I will consider it.
