qq: do people need to run this outside of this pkg? I guess not since you put it
in src/ :)

exactly, no need to run this in other packages. They will need a different
transformer to generate code, but this one particularly will be hidden.

With this hidden transformer we end up having everyone using the mirror
implementation when developing directly in Dartium by default, but mirrors are
removed behind the scenes whenever you use pub-serve or pub-build.
