A limit will barely lower bandwidth.
Rarely there'll be a mapper that will ever hit any limit whatsoever in the first place. Not only does the time it takes to grave something take a while, but for someone to hit such a limit, they'll already be a longtime member in the community. It'll only affect a very, very small percentage of people who simply upload something with no intention of getting it ranked, and surely no one is going to do that twenty or so times. The community isn't trigger-happy with their uploads enough to warrant a quota.
Not only that, another definite qualm would be that the amount of "map-switching" would rise. Map-switching's the act of completely changing an old beatmap into a new one. This sort of thing is nukable, especially as the stars are transferred in the process. An infamous case of this would be Nekomiya Nono's map. If there were to be a Graveyard limit, paranoid mappers or mappers facing that limit would definitely just ask to revive some abandoned graveyard map and switch it out into a new one.
There's little to achieve coming from this, personally.
