Two large reasons why D is not focused on ABI compatibility:

1. Most of Phobos is templates. Template signatures can change easily 
from one version to the next, even if the template didn't change. C++ 
has the same issue.
2. D is generally statically compiled, not with shared libs. There is 
some progress on this front, but really, until the shared library 
support is mainstream, then having binary compatibility between 
releases, and therefore ABI compatibility, is not critical -- you have 
to recompile anyway.
