dw and --extra-depends have slightly different semantics,
usually used in a case like this is dw.

IMHO the only effect of your suggested changes would be decreased readability.

When you use ANY, wb will create 19 wanna-build commands per package for 
the 19 architectures.

Pasting/Piping many commands is not a problem in practice,
a change to ghc and there are > 1k nmus per architecture.

The above 26 wb commands are readable and trivial to paste,
I would recommend against trying to optimize anything here.
