I forgot to add that, AFAIK most complains about Dub center 
around:
A) dub-registry availability
B) dub being used as a build system, in addition to being a 
package manager.

A) Could be addressed by:
1. Downloading packages from GitHub, GitLab, BitBucket, etc. 
instead of storing them on the dub-registry server (or at least 
have this as a fallback option)
2. Providing a copy of the list of packages in an alternative 
form and on alternative places (e.g. the list could be stored in 
git repository, mirrored across various providers)
3. Using other package registry services as backend (e.g. Dub has 
Maven support)

B) Is not a showstopper as people can continue using their 
favorite build-system, and have dub as build system be improved 
at the same time.
