But the import issues weren't solved with warnings, they went 
strait to deprecation.

And I'd argue that warnings are an unnecessary step in the 
deprecation process. IMO the deprecation -> undocumented -> 
removed cycle for Phobos works well. Adding another step to it 
needlessly delays the inevitable (how long has array.sort been a 
warning?), and I don't see why the same process won't work for 
DMD.
