I'm not sure that bugs are an issue so much as design compatibility, 
which would be a real problem if strict backwards compatibility were 
necessary.  Tango moves a number of public Phobos modules into the 
runtime, and these simply could not be re-exposed.

For what it's worth however, there is already a 1.x implementation of 
Phobos which is compatible with Tango: Tangobos.  It's even publicly 
maintained.

Yes it will, and likely a bit faster now that Brad is involved in the 
Phobos side.  But there are a lot of issues to resolve and we've all 
been short on free time recently, so I don't want to predict how long it 
will take either.
