It's more than a proposal. ECH is defined in RFC 9849. It's live and in use.

It hides the SNI from passive network snoopers. I think that's a good step
forward.

I don't know what that means, but to me that is irrelevant here. c-ares is the
only way curl can resolve HTTPS records until someone adds support for another
DNS library, but then I would also love to learn why that other library is
better for this purpose.

It is up to everyone who builds curl to decide wether to use c-ares or not.
