> I agree with Nick, this is indeed big, but not impossible. If you
are not sure yet whether you will work on implementation, you can focus
on polishing the PEP text, and then if it is accepted and you will
decide to give implementation to someone else, we will find a volunteer.
Unless I'm misunderstanding something, it seems that the OP is under the impression that because they authored the PEP, they're obligated and responsible for the entire implementation. Instead, we should be able to relatively easily split up the implementation into multiple self-contained PRs. The OP can still work on some of them if they want to and are able to, but other contributors can work on other parts of it.
The easiest way of doing this would likely be separating each self-contained PR into a bullet point in a bpo issue with a brief description (similar to the layout posted above), and then the OP can work through them as they have time to do so. Any other contributor can simply pick up where the OP left off, or on other parts of it while the OP is working on something else. This would of course be after/if the PEP is accepted.
