I am attempting to write a compiler in D2 (github.com/bhelyer/SDC), and I 
can't help but feel that rewriting druntime, or picking out the 
relatively benign parts would be a difficult, bug filled task. I don't 
see a realistic alternative to druntime compatibility.  I also feel that 
having all implementations share the GC implementation means that 
improvements there will improve everywhere else. If I weren't to use 
druntime's GC, then I would use the Boehm collector, but I feel using 
druntime is more beneficial than not.
