Personally I'm happy to leave those particular messages as they are.
Yes, a case could be made for changing them to say "LSN", and a different
case could be made for changing them to say "WAL location", but I don't
think either of those are real improvements. Also, this'd be propagating
the compatibility problem into yet a new place, because there are surely
user-written scripts out there that grep the output for exactly these
spellings.
It's a judgment call though, and others might have different opinions.
