I don't know that this is entirely fair--you paint the existence of 
Tango as annoying in three entirely different ways :-).  That said, code 
compatibility issues are (hopefully) not a long-term problem as people 
will either port their code or they won't.  What worries me personally 
about presenting option C as an official alternative is that it places 
us (ie. the Tango team) in a position of supporting a Phobos facade for 
a potentially indefinite period.

I think it would be more the reverse.  A library that looks like Phobos 
but calls Tango at the bottom layers.  But it's still a lot of code to 
maintain that has no direct relation to the project.  Perhaps such a 
thing could be created and managed separately?
