The idea with this is instead of separate add-bindings commands and trying to maintain a unified and stateful WIT file, the add command should generate a WIT file per dep and create bindings for that dep in a separate Rust module. This seemed to work nicely enough for simple cases, but ran into some nasties when the dep imported an interface that got subsetted (and was used elsewhere with a different subset? My memory is vague). Anyway sending the PR at @karthik2804's request for him to to include or adapt as he sees fit!
