Yes please do. As in (info "(elisp) Quitting Windows"). Which you might
as well add a link to...

OK, but there really should be a way. Else heavy dired users commonly
end up with plenty of old buffers by the end of the day.

(Note that if they toggled the default to now kill, instead of burying
the buffer, they would need a way to make an exception. E.g., the argument
would then instead bury, not kill.)

(Also let's say they have one or two dired buffers they really do want
to keep around, despite their "q" hitting habit.

Well then perhaps there should be a "dired-mark-this-buffer-as-q-kill-proof"
command... Or maybe even a regexp list that the user can put in their
.emacs file.)
