AFAIR those modes derive from c-mode, right? It that is so, the commands
are automatically applicable to them.

Why at runtime? (apart that compile-time and run-time is a somewhat
diffuse distinction for Elisp) Can't the mode have declarations like
thos I mentioned?

But apart from that, I see no big problem about changing the list of
modes at runtime, although I don't know the current implementation, so I
hope someone else can clarify this.
