I would urge you to search for similar functionality already in the ecosystem. If your package is mostly covered by other things already out there, I would suggest refraining from registering it unless there is some significant advantage to the community in the way you’ve done things.
If you just need to register something for reproducible research, you can always start your own registry. My group has done that. IMO General means “of general interest” and using it to document a specific paper seems like an abuse to me.
