I like Tony's recommendation - except that I'd rather not ‎lose the 571 curve. But I'm not going to fight the entire WG over this.

It's the most used of the rarely used curves.

I think all "rarely used curves" should be removed from TLS. Specifically, I think it would make sense for TLS to adopt a curve portfolio like this:

- CFRG curves (RECOMMENDED): Curve25519, Ed448-Goldilocks
- NIST curves (SUPPORTED): P-256, P-384, P-521

All other curves should be removed, IMO.
