It seems odd to move this file to ash/ but keep the ui::namespace...

Oops, I forgot my TODO. Added. I would prefer to do this in a separate CL
because it touches dozens of files in hundreds of locations.

Is that OK? Or would you like me to do the file move/namespace cleanup in a CL
before this one?

Yeah, a followup is fine, I can do that namespace change if you want.
