Excellent!

I would prefer if you call it System.Console.Editline to begin with,
even if it doesn't support the full API yet, so we can already
start migrating our code.

If you want, you can also include System.Console.Editline.Readline
to provide some Readline-compatible wrappers for the new API
where possible. That might help some people with backward
compatibility. But for me that is a lower priority.
