It may be a good idea to make sure that issues related to 
single-version dependencies are fixed first, e.g. 
<https://github.com/dlang/dub/issues/1732>, otherwise we risk a 
situation where multi-version dependencies are created 
unnecessarily.

BTW, why is this considered _vital_ for moving phobos to DUB?  I 
am not really convinced that Rust's approach is a solution -- it 
feels more like a dirty workaround that will have plenty of pain 
points of its own.
