The above categories in portage contain no metadata.xml file. Request to have them added. Reproducible: Always Steps to Reproduce:
These categories were added for the currently-masked X-modular. I'm not sure when Donnie wanted to work on setting up the metadata (or if he is even waiting for anything), but my guess is that his original plan was to wait for upstream to stabilize.
I've already added metadata for all the individual packages, but we need to come up with a few category-wide metadata files too. That should be pretty easy.
