• gcloud on PyPI would include "core" modules.
• gcloud would (maybe) become a namespace package
• Each API would have a separate PyPI "project"/releases

Cons (mostly for maintainers):

• separate release cycles
• More complicated CI
• Might need to split repos?

Pros (mostly for users):

• "Hard" dependencies for each API (gRPC, I'm looking at you)
• Separately updateable distributions
• "Pay only for what you eat"
