That's true for all these schemes.

The important question is, what does the name _mean_? With the current
scheme, "/dev/sdb7" means "the 3rd logical partition on the 2nd SCSI
disk". "/dev/hdb7" is a little better - "the 3rd logical partition on the
primary IDE slave disk".

What I proposed was something meaning effectively "the filesystem I mkfs'd
on 1997-12-17 13:55:21.765".

See the difference?
