As I described as above, I don't see obvious use case where ONLY

not only clears backup locations but also inhibits resetting xlog
infos which would be done without the option. The behavior would
puzzle users.

I'm not so knowledgeable about ancint(?) specs:p Of course this
phrase means "back to 8.4 that this patch has any meaning".
