This reduces iteration time (`make rustc-stage1`) for moved syntax extensions from 11 minutes to 3 minutes on my machine. Because of the signature change, this is a [breaking-change] for people directly calling `expand_crate`. I think it is rare: from GitHub search, only case I found is [glassful](https://github.com/kmcallister/glassful).
