Thanks Ivan! Seems handy. Would it be easy to include a comment (like your pull request comment) in the file? I'd like someone (or, myself in the future) to be able to look at the library.json file and say answer "what is this / how do I use it? do I need it for Arduino? Is it still needed / up to date?" Links to external docs are great for any of those.

I'm curious about the platformIO registry. Is that reading from your branch of this repo? Since that page already exists, I'm wondering what the library.json file in the pull request will do (it looks like the registry page and that file contain the same information).
