What's wrong with by-id, by-label, by-partlabel, by-partuuid,
and by-uuid? At age 11, I spent a lot of time DXing the AM broadcast
band (trying to receive and identify radio stations on the AM dial
540khz to 1700khz). When I received and identified a station, I'd
create three index cards to put in three metal card files. One file was
sorted on call letters, one on frequency, and one on location of the
station. That way I could find all stations I'd received on 550AM, all
stations I'd received from LA (I lived in Chicago), or where station
KDKA was from.

Now, every relational database enables you to look up rows by
searching any column, and indexes can be created to make such lookups
efficient for a given column.

I find it handy to look up disks by label, uuid or device name. I don't
see a major disadvantage.
