Nobody has an ECSDA cert *signed by a trusted CA*, i.e. something that a
browser will connect to without setting off all sorts of alarms.

It's the common case based on a survey of all (known) publicly-deployed
servers running TLS-ECC, representing (at least) Microsoft, Apache (presumably
OpenSSL), and NSS.  That's the three biggest players in the market (and some
smaller ones as well), so I think it's a pretty good representative sample.
