Deprecate and remove, please. We've been removing these sorts of things
over time, and nova hooks have been ignored in that process. But really,
making them more rigid is going to get in the way over time, trying to
continue to honor an interface that codifies internals at a certain
point in time, and leaving them as-is will just continue to generate
issues like the quoted bug.

I don't "lean" on deprecation, I feel strongly that these should go away.
