As others have said, it's about _being able_ to
have different behavior.  It's not about changing
the default of having the same behavior on both.

I agree with what everyone else (so far) has said
about this.

It is good to be able to use `C-[' to get `ESC'
behavior, just as it's good to be able to use
`ESC ESC' to get `M-x' behavior.  What's not so
good is to make it hard to get different behavior
for `C-[' and `ESC'.
