We were actually talking about the same thing.
When I saw "introspection", I brainfarted that you were meaning
that some people might be using MOP
to inspect methods for subclasses of OPERATION.
But you just meant new methods on OPERATION for the sake of inspection.
Once again, you can see what's in quicklisp:
>> less -p 'defmethod.* operation)' $(grep -il 'defmethod.* operation)'
Plus POIU has a few of its own.

My point is that we already had a "good" way of enforcing it:
very bad documentation, such that someone trying to do something
would have been ill-advised to do it without consulting the mailing-list.
As for loners who refuse to contact the mailing-list?
Well, their code will break, and they'll fix it without talking to us. Good.

Future scholars will only have copies of copies of copies of manuscripts.
How will they authenticate what really WAS said in our dark ages?
