Backporting to what? To PCRE1? That is now 3 years out-of-date.

I'm sorry, I don't understand the question.

When NULL is a valid value, it is usually mentioned. The ..._free() functions
were an exception which is now rectified.

Which functions? Several functions allow *some* of their arguments to be NULL,
see for example, pcre2_match(), but I can't see how listing them separately is
useful. (And it's hard enough already keeping all the documentation up-to-date,
without adding any more. :-)
