Valid requests, but I think I can promise you only the first one =). The 
easy-to-use would be nice, but as we've discussed, perhaps the core 
bindings should be, well, core, which doesn't always equal easy to use.

And the third one... I'll try to keep backward compatibility when 
possible (at least for a period of time), but that's just not always the 
case.

The v2 series goes back to that, although the code behind is a bit 
different.
