I agree with the last sentence.  Happy Eyeballs is about the HTTP. 
There are other applications protocols too. :-) 

Happy eyeballs is about HTTP. But part of the approach predates "Happy
Eyeballs" -- please see RFC5461.

It's certainly true that we usually talk about Happy Eyeballs in the context 
of HTTP, but I use it for ssh as well, and I think it's applicable across a 
broad range of application protocols.   It is not applicable to _every_ 
protocol, but that's as strong a qualification as I'd put on it—saying it's 
only applicable to HTTP is not correct.


Exactly. For instance, I seem to recall benefiting of RFC5461 for ssh in
NetBSD long before the first version of the Happy Eyeballs I-D was
published.

As noted in RFC5461, the approach is useful for any protocol -- but for
obvious reasons the benefits become evident for interactive protocols
such as HTTP, SSH, telnet, and the like...
