Document abandoned features #196
Description
Let's (briefly) document the features we have stopped developing some time ago, but haven't removed from the codebase. These are the ones I can think of:
- OCI mode
- Rootless
We want this to be detailed enough to be helpful for someone who gets across these features in the codebase, but not more than that. No one will ever need to change these features, although they might want to delete them at some point!
