Sorry for being slow to return to this, I see you have already committed it.
FWIW, I do agree that this makes a lot more sense.  Retroactively +1’ing it.

Regarding the core code I agree that no callers directly benefit without some
refactoring, but contrib/xml2/xpath.c has one case which seems applicable as
per the attached.  Now, since contrib/xml2 has been deprecated for a long time
it’s probably not worth bothering, but it was the one case I found so I figured
I’d record it in this thread.
