...which is what I do at the moment. Level geometry does have advantages for which, sometimes, I'd like to use it instead of models, though

Seems as if we had to wait for whatever update will be next. The only question left is, does anybody know whether level geometry is going to be improved with BSP as well or will only Octree be able to use upcoming improvements? Obviously, it is not BSP that is so slow about it currently, is it?
