Honestly, part of the reason I don't play LE often is due to the fact that you cannot get experience on it. I can understand why though with farming maps. So I want to suggest something that may take time to do but could be nice.
Basically, if a LE map passes a quality test of sorts, XP would be allowed to get when playing on the map and even get a visual marker that you can get progression playing it. This mark would be manually given instead of automatically assigned so people cannot easily find a way to cheese the system.
A map cannot be a coin farm map, have closets or whatever in the basement, be able to be finished by the developer (they will have to be able to play their map and at least be able to enter the basement completely.) amongst a few other things.
If anything I imagine the maps that won the old LE contest should be able to get progression already even if this system doesn't truly get added.
