The goal is to avoid importing code into a process that is not going to
be used. Not because it is slow or uses a lot of memory (in my testing
it is not slow, I'm unclear (thus far) about memory use) but simply
because it is inappropriate: Any single process should only contain code
(and config) that it is actually going to use.

Good to know, thank you. This seems to be the growing consensus.
What's not yet clear is how soon we'll be able to make this happen
but at least we know we'll be trying to make progress in the right
