The issue we're going to run into is that a lot of extension authors
like to call things that the core developers probably think they
shouldn't. If we lock it down, we'll either be breaking a bunch of
extensions that are doing sneaky things that somebody has managed to
make work ... or we're going to be committing to an API that we don't
really want to support.
To be clear, I'm not saying you're wrong, just that it's going to be
hard to change anything without making somebody unhappy.
