In maintaining Derelict, which is nothing more than a simple collection 
of bindings to C libraries, I have had headaches keeping compatibility 
between D1/D2. It's nothing that has been difficult to solve, just ugly.

If something as simple as a C-binding is uglified, I cringe at the 
thought of maintaining something more complex. It's going to get very 
ugly, very quickly. My attitude is that any future D projects I make 
available will be D2 only. I just don't think it's worth being 
compatible with both versions from a code maintenance perspective.
