I was thinking about having people register for notifications 
themselves.

I need something similar for dev/testing purposes as well. Since 
I am using digger it is really easy to build whatever dmd + pull 
request is needed. Problem is controlling access.

Nice find. Will use.

Sure.

I am not sure this is a good idea. Besides the fact that coverage 
doesn't correlate with quality, it is outside of the purpose for 
this tool (identifying dmd regressions and identifying broken 
packages).

I rather hear it from people than seeing it in the stats :)

It is an open problem and I don't wont to solve it. For now I 
think I will just install the most important ones and just accept 
that not all packages will be build.

On another note, I do think the dub package definition could use 
some extra fields. Like compatible platforms and compatible dmd 
versions. Take vibe.d for instance, it is specifically build for 
certain dmd versions and it makes no sense for dubster to try to 
compile it with an unsupported version. Also, it allows dub 
itself to notify you of incompatible packages w.r.t. the 
installed compiler. Same idea for platform.
