It is *possible*. OTOH (local-set-key "\C-[" 'foo) does not work, which
is an obvious bug on my book. If it is a bug on the implementation or on
the documentation, is another topic. (for me, as an user, it is a bug on
the implementation)

Please don't add emotion or hidden intent to written expressions on
technical forums, it poisons the discussion.

Sorry, but this makes no sense. Nobody is asking for a change on the
default bindings, what we are saying it that the user should be allowed
to set the binding the same way he does for any other binding. It is not
reasonable to expect from the user knowledge about ancient technologies
and the limitations they imposed on the Emacs implementation that deals
with them.
