I guess you are referring to the fact that src/data.c contains

  DEFSYM (Qbuffer_or_string_p, "buffer-or-string-p")

This is used in CHECK_STRING_OR_BUFFER in textprop.c.
The simple presence of the DEFSYM is not by itself motivation for the
addition of a "buffer-or-string-p" predicate.

If you think such a thing is needed, you need to eg show how many places
in the current lisp sources would use it. And then if added it needs to
be documented too.
