this is really really difficult.
For example, you added the rg353p, rk503 nad rg353vs and their aliases
two years ago for 6.1 , the rg353ps for 6.5. So someone might actually
rely on those already in their userspace setup.
So reorganizing the aliases to point to different devices might actually
break userspace, which as you might know, is sort of a big deal ;-) .
Userspace programs can determine the mmc mapping via the board-compatible
though.
