Uh, the kernel doesn't care what the device names in /dev (or elsewhere) are.
It deals with major and minor numbers only.
The problem is not assigning arbitary (file) names to (major, minor) tuples.
The problem is assigning logical drives in an open environment where any
number of third-party controllers could pop up on any number of slots in
any number of different busses and having the whole thing work if you exchange
a given controller for an incompatible one.
This may just barely work out in the playpen of proprietary systems but in the
real world things aren't that simple.

We don't have that limit anymore.
