Only real reason for long or mid cage is for taking up excess chain. If you have a "pinecone" rear cluster, of say 22 or 24 to 11 teeth you do not need a mid or long cage, if you are running a cluster with say a range of 32 or 36 to 12 or 14, then a long cage is required, a short cage would not be able to handle the amount of chain for the gear spread.
Even with 3/4 inch ground clearance for the bottom pully, I doubt you would scrape the derailure, unless you drop the bike. Lean a bike over sometime, and you will see what I mean, unless you slide the bike, the derailure will not touch the ground.
