I don't see how creating a separate mode for "new maps" would change something. Most of the maps that have been made by the players over the years, and that are already in the server are played with a constant rate, and to be honest i gotta agree that some of them are pretty cool. The problem comes when you have to build them, because the risk of building bad or bugged maps (bumps due to bad placed streets, invisible walls, bad placed objects) is pretty high, and it simply takes too much work to build even a single city that can give place to few races (i doubt you can build a lot of race with a map that is quite small, at one point you'll be forced to use the same turns over and over again). Some months ago some of you guys wanted to ban time trial from /bm, and since that i haven't seen so many new races with GM and Merge, so be sure of what you're asking for. On the other hand i'm in favour of adding Ghostmode to World races, and maybe edit some of the already existing TT races to merge and GM.
