Yes, that makes sense.  If we do add a "Really execute this command from
this other mode?" thing, then being able to permanently disable the
warning, like with disabled commands, would be nice.

That does seem natural, doesn't it?

However, I'm not quite sure about the proposed usages for using
completion-predicate for commands that are currently not usable.  In
menus, the commands are still there -- they're just greyed out, so you
can tell that if you just do something (mysterious), then they'll be
enabled.

In `M-x' completion, that's not really a natural...  thing?  (Unless
using a display method that displays all completions, no matter what the
predicate, but sort/display/colour them differently, as Eli suggested.)
