Most of the code is under the LGPL license, not in the public domain. The build files are under BSD and/or public domain and BDL and/or public domain for documentation. FWIW being in the public domain with sources available is considered free according to the FSF (not the OSI apparently).
I don't think it's really weird but using it as an http rest client for testing apis with restclient.el
Postman frustrated me because it was taking up all the memory on my computer to do really simple calls. I remembered the "emacs rocks" episode on restclient and gave it a shot. Such a nice package. Really unfortunate that the maintainer doesn't update the melpa package.
I use emacs restclient as well. It's not just good - it keeps you in the flow. No context switching to a different environment, just a quick cut 'n paste of the path and data you're working on.
Melpa package still misses restclient-jq.el AFAICT, the receipe for the package is not correct. Seemed to work at some point since someone merged a PR about that.
I don't think it works for everyone, but I've read a lot of good from people religiously applying the GTD[0] method. Though it is a very strict method and a lot of people will get discouraged quickly when trying to apply it.
