that prevent them from being valid JSON ones.

The files are hjson and not json. The format isnt as strict, and allows content such as comments. Content that would fail most json parsers.

If you need json, then you should be consuming the converted files from the API endpoint (For example https://keyboards.qmk.fm/v1/constants/keycodes_0.0.1.json).

This includes any processing that happens with merging content, avoiding the consuming process having to duplicate any of the lib/python logic.
