My opinion is that they are very nice certs indeed and it would be
lovely if we could all use them for everything, but we're probably a
few years away from a point where a server admin can be confident that,
say, 95% or more of potential visitors will be on systems where this
will "just work".  In the interim, ECDSA certificates using the NIST
curves (yes, the ones everybody is suspicious of) are probably the best
possible trade-off between small size and good support.

I've finally started work on my little super-simple certificate
generator.  By default it uses ECDSA with the P256 curve.  You can feed
it an option to use ED25519 instead.  That's it, there is no support for
RSA.
