The original use-case was for DTLS, wasn't it?  We only have a single registry for extensions, and that's reasonable since the vast majority of them are applicable to both TLS (TTLS? :) and DTLS.

I think it makes sense to add another column to the extension registry, called "applicability" or something like that with values from the set (both, tls-only, dtls-only) and the default is both.

It's not just out of vengeance, honest! But I think TLS heartbeat should be at least be deprecated in 1.3.
