Nice work. I wonder about some of your results, as it says that 
dub itself doesn't build with all of the dmd versions, but 
somehow the tests pass sometimes (shouldn't be possible if you 
can't build dub itself). I just tested with `dub fetch dub; dub 
build dub` with the dub 1.10 that comes alongside dmd 2.081.1 on 
linux/x64 and it built the latest dub 1.11 without a problem.

Regardless, you should talk to Sonke about getting this 
integrated with code.dlang.org and to Mike about putting up a 
funding target to pay for both permanent server resources and 
your time coding this up. I've already said I'd donate towards 
such a target:
