Unfortunately it only worked for hard disks because the old name
space was abandoned entirely. It also caused a lot of surprises
for people upgrading their kernels, which is something we probably
don't want to repeat.
Now we could add a new dynamic registration facility to the tty
layer for drivers that don't already have a name and dev_t
associated with the driver, and then use it for all new drivers
as well as those that intentionally want to convert.
With DT aliases, we already have a way to enumerate serial ports
across device drivers, so if we are going to do something new,
we should make sure it works with the numbers defined there.
