You really hate QBS don't you ? :)

Anyway IMHO is more important to have a clean, nice and easy to use syntax and 
to be tooling friendly than 1.b.

GN[1] is another example of build system which didn't care too much about 
1.a,b,c and it still used in quite big projects (e.g. chrome, fuchsia). To my 
huge surprise, they managed to move it into a separate repo and remove all 
chromium dependencies (yep, a few months ago you had to checkout the entire 
chromium repo to build it :) ).

Cheers,
BogDan.
