Hello, hope you're having a nice day,

It is unique; however, I'm not talking about it being unique. More like 
from a  console standpoint.
Imagine your system's asking for manual input for the root partition; 
what's easier to type - /dev/ufs/root, 
/dev/ufsid/{inserthugenumberinhexhere} or /dev/physical-device?
Reading through /etc/fstab when it uses ufsids is a pain as well.

By the way, in my opinion the current freebsd install system should 
allow running GEOM commands before partitioning/labelling devices. And 
should also recognize GEOM devices, as well, since for a clean install 
the transition to labels & gmirror is either 'not safe' 
(kern.geom.debugflags=16, then label the live system's drive) OR 
requires a dump/restore (label the 2nd drive, label the partitions, then 
copy data there, reboot to the 2nd drive, add the first to the mirror).

P.S. Also, bsdlabel and glabel seem like ambiguous names (as well as 
using the term 'label' for both slice layout and GEOM labels) - so I see 
no problems naming AHCI devices "daX". ;)
