I agree, but I'm also trying to say I can't unilaterally declare
pieces of our internal structs to be covered by an ABI guarantee.
Maybe the rest of the ABI will never change because it'll be perfect,
but I point to the immediately preceding thread as evidence against
the likelihood of perfection on the first try. I'm trying to build in
air bags so we don't have to regret a mistake.

It's still required _during_ an ABI bump, though, if you don't want
things to break. Right?
