It is about whether both A's can be installed and coexist on the same 
machine.

Same as above. You have B.1 -> A.1 and B.* -> A.2. You want to install 
both A.1 and A.2 and work on B.* while checking on B.1.

In the long gone time of common sense, a project code management system 
would use a virtual file system and map different parts of the projects 
graph onto a structure of folders arranged by versions. Today one would 
use something ugly like a virtual machine or incredibly ugly like a docker.
