One of the reasons for using Bacula is so that you don't have to track what 
Volumes it is using. It does all the work for you, and if you trust it, you 
won't need particular Volume labels.

That said, If you really want to use Client based Volume labels, you can, but 
to do so, the only reasonable way is to work with Pools and either prelabel 
your Volumes, or use some labeling scheme such as you did.  If you do not use 
Pools, there is no way to absolutely guarantee that Bacula will write on a 
Volume you have just created.  With Pools, at least you can guarantee that it 
will write on a Volume within a given Pool.  There is a whole chapter in the 
manual describing this for Full, Differential, and Incremental backups, which 
can be easily extrapolated to Clients.

So, in my opinion, it isn't so much a question of a feature being "worse than 
useless", but rather learning which features will accomplish what you want.
