Do you want to add a comment somewhere explaining why this is the case, like a
go/ link or a bug # that explains the refactor that is underway? I think we're
going to have this situation a lot and it might help other people understand why
their DEPS checks are failing.

I wonder if we should leave some kind of note in BUILD.gn, or a README.md, or
something like that too.

I added a README.md to ash along with a pointer here.

This is in the include_rules above.

This is a short cut to allow the aura files to include all files. I could have
instead explicitly added back the _aura.h files listed on 6 and 7, but this
seemed easier.

Ah, OK.
