That's what happened in the past and we changed it, so clearly we're not
going back there.
Toggling non-interactively is a very rare need.  But you can do it with
(foo-mode 'toggle) if you don't like (foo-mode (if foo-mode -1 1)).


PS: In case you wonder about the reason for the change, it's for
(add-hook 'foo-mode-hook 'bar-mode), eliminating the "need" for those
otherwise redundant turn-on-foo-mode.
