Want to remove this.

I'm not sure if we can remove this. As long as we don't introduce aggregated
bindings (I think we decided not to introduce aggregated bindings for dictionary
impls), we'll need to write a list of generated files somewhere.

Yes. We don't use aggregate build for dictionaries. Seems that I need to list
the generated files. Thanks!
