Usually I would agree to this argument. However, we are talking about 
projects to provide an Ada interface for a GUI toolkit written in another 
language, not about a project to actually _develop_ a GUI toolkit.

Any reason why all of this can't be achieved by a single project?

That's IMHO another reason to have only one project. At least two persons 
have used much of their time to achive more or less the same goal, which is 
really great, but in the end both projects lack important functionality 
which is present in the other.
