That may be, but that train has left the station a long time ago.

The problem is that there are related symbols for which mirroring is not
defined, and defining it for the half stars would make for an
inconsistent solution, unless any other vertically divided symbols were
mirrored as well.

I don't believe any of them are.

Adding mirroring after a character has been encoded effectively renders
all existing documents incompatible, so it's a property you can change
mid-stream.
