You add this license, but then never actually reference it in the later
changes, so it's going to be very confusing as to why it is here.  Any
way to add it to the font files themselves so our checker tools can
handle this properly?

And, it's not going to work as a dual-license, you can't just suddenly
dual-license those font files, right?
