My understanding is that the pluggable type system would allow for 
alternate implementations for a given GType.

If that is the case, then the implementation code for, say, a 
GtkTreeView might differ in a 'pluggable' environment from the stock 
gtk+ implementation treeview code. If this is the case, the gail code 
will almost surely break; this is because, while gail uses public gtk+ 
API for its support (thus the API would be the same in a pluggable 
environment), gail does currently depend on implementation/behavior 
details of stock gtk+ widgets (i.e. order and type of children, perhaps 
signal emission order, etc.).

Not sure I agree. But then, perhaps I have the wrong concept of what is 
actually intended by a 'pluggable' type system. If so, please feel free 
to enlighten me (on or off-list).
