It has been proposed before, yes. I've not seen anyone get sold enough on the
idea to actually provide time and energy to make it happen. I'd estimate it to
be a significant chunk of work so it'd take someone with a real desire and use
case to pull it through.

The only attempt to roadmap that we have in this project is this:
https://curl.haxx.se/dev/roadmap.html - which is just mine and Steve's ideas
of what we wanted to work on when we last updated that document. Then there's
the TODO document (https://curl.haxx.se/docs/todo.html) that lists ideas that
could worth exloring further. None of them include CoAP =)

I consider the lack of interest to implement this into "the popular libraries"
to tell something as well. I am personally a skeptic of the long-term future
for the stripped down versions of real protocols that I consider CoAP to be a
representative of.

I wouldn't mind exploring that and see how it could be done and get
integrated, but I'm not personally going to do all the work. It's not a use
case for me *personally* that I have a need for.
