No.

No, don't really use the official repos anymore, been using the 
LDC forks instead, so doesn't matter to me how the official git 
repos for dmd are organized.

LDC splits off the DMD testsuite as its own git repo too, so any 
merged directory can always be split off to another git repo if 
wanted:
