Hi Jarek, I've now written a short proposal:
https://wiki.openstreetmap.org/wiki/Proposed_features/Tag:usage%3Dirregular Please feel free to edit the wiki page directly. By the way, i found an example of an underground and of a light train diversion-only track. I'm still a bit unsure if these tracks really belong to the usage=* instead of the service=* key (it's still used for public transportation, not for industrial, military, test or tourist purposes) and if *=diversion wouldn't be clearer than =*irregular.
