If it's just that, I can probably provide a patch for

It would be premature until there is more agreement that your proposal is sound.

I don't want to quote your whole email, but I do have an important piece of advice. Asyncio was designed explicitly to disallow recursive event loops. You may think they are important based on what you've done with other event loops in other languages. But changing asyncio to allow recursive event loops would require a very serious reconsideration of its design.

Based on your project description it looks like you should ask somewhere (not python-ideas) for advice on how to best structure your gradual migration within asyncio's current limitations, rather than trying to propose deep changes to the standard library.

Sorry the news is not better, but you will be better off this way.
