Yes, compiling package-at-a-time should be the mode endorsed by the core 
community. Liran Zvibel and I discussed this privately following his 
DConf 2015 talk, and I recall he mentioned the package-at-a-time solved 
essentially all of their build problems.

It would be fantastic if somebody could write a wiki/dlang.org article 
about this with details on how to do it and measurements. One prime 
example is Phobos itself, for which conversion to package-at-a-time 
build (http://forum.dlang.org/thread/mkvpgn$2fg3$2@digitalmars.com) has 
led to dramatic improvements in memory consumed and build times 
(https://github.com/D-Programming-Language/phobos/pull/3379).
