Probably not for 24.1 indeed, but the first usage I looked at is in
files.el and it duplicates the same logic wrt mode-class:

(when (and buffer-read-only
             (not (eq (get major-mode 'mode-class) 'special)))

I'd guess (with no data) that most of the other callers either use
something similar, should use something similar but did not think of it,
or would not be affected if something similar were added.
