Thrashing out details should go on the workflow SIG, and I guess I'm the obvious candidate to push it asking. But given my own time constraints right now, I'm not going to dive into details if the high level concept (stdlib packages can be individually updated by end users apart from a full CPython release) is at issue.
Once there seems to be general agreement that this is a worthy goal, I'll see if I can put down details for how I would implement it. (And go join the core-workflow list, I guess :) )
