I think it makes sense to have a next-error group for other modes.

Is it time to make next-error a minor mode with its own next-error.el
file?  It seems like a useful thing, instead of manually hooking it
into all the user modes.  The minor mode could provide hooks that
would replace the current code; this would also facilitate adoption
by other modes.
