It's DUB's "optional": true broken ?

Assumption: dshould has 2 configurations. In first configuration, 
unit-threaded is marked as optional in second it isn't. Dub 
therefore downloads it per rule (all configurations are 
considered, also the not used).

The author could mark it in all configurations as optional or, 
use sub packages, which is another way to have optional 
dependencies.

Kind regards
