I'm trying to follow @PeterDaveHello advice from #3941:

@ clayreimann we'll need much more time on the discussion about how to handle the files, but at the mean time, actually you can submit a PR on GitHub with only a single package.json, please take a look at #7149

This is my first time sending a library to cdnjs, so I could've made a mistake, sorry.
