I was more thinking of ent files to fix, balance and improve older maps (temporarily) I've already started to create in 2011.
However, this feature vote for the mapinfo files is useful, too. Maybe ent files should be a different feature vote, because these shouldn't work from a central repository if a server have it's own file. That would destroy deliberate changes, e.g. full player equipment for speed server. It's a little bit different.
