If you find yourself creating a lot of single-use abstractions, I think you're probably doing something wrong. In particular a lot of containers (I know Autofac) support Func<> very well. As for ceremony and semantic load, I can't argue here, though I think following DI restricts some of the semantic load that comes with abstracting mainly through inheritance and through managing stateful dependencies.
