I think that this factor might be the ultimate source of my discomfort with standards like REST. Things like using HTTP verbs and status codes, and encoding parameters into the request's URL, mean that there's almost not even an option to choose a communication channel that's lighter-weight than HTTP.
Nobody does REST, because nobody needs the whole hateoas shtick. When people say REST, they mean "HTTP API" and I'm not being pendantic here. The difference is very real because REST doesn't really have a reason to exist.
