I guess the issue is that it's pretty difficult to get an include-list
here:
;; Most of the temp buffers in the background:
(major-mode . fundamental-mode)
;; non-text buffer such as xref, occur, vc, log, ...
(and (derived-mode . special-mode)
(not (major-mode . help-mode)))
But... I think this is way too dangerous -- I think you really have to
come up with a include-list instead of going after fundamental-mode and
special-mode buffers.
