Sorry, we have so many bad examples in this file for you to follow...

We are trying to avoid all_dependent_configs as much as possible. This is
strongly opposed by gn folks. So we should actually fix the
:media_dependent_config entry we have.

In your case, will public_configs work for you? If public_deps works, it should
work.
