You probably got a better response on how to call
canonically-space-region with point-min and point-max, but it's good
style to call elisp code that indirectly manipulates the point or mark
inside a save-excursion block as well.  (text-mode-hook might get called
in a context where the point is assumed to be somewhere else, like the
start of the message body.)  The help I have for `C-h f
mark-whole-buffer' states that "it is usually a mistake for a Lisp
function to use any subrouten that uses or sets the mark".

Not a Gnus question per se, but kill-buffer-hook gets called with the
buffer being killed as the current buffer, so you can look at
buffer-local variables like major-mode to see.
