Exactly.  Of course, it may be that some hook somewhere ends up calling
a major-mode every time we run a command, which could lead these things
to be constantly re-added to post-command-hook.

Still: even running all those functions all the time shouldn't slow you
down, unless one of those functions takes a long time to execute.
