Actually it has. There is Avalon and Avalon is supporting the products 
your using.

Fortress/ECM represent a product family within which there are specific 
semantic assumptions.  Those assumptions need to be drawn out to a more 
formal specification (and possibly supporting object model) as part of 
the Avalon development.  The Phoenix/Merlin style of component 
management represents a different set of assumptions.  The 
Fortress/Merlin development has brought that a lot closer, but the end 
game is the single product that incorporates cleanly and consitently 
these differences.  Reaching the common solution is the migration 
process I'm talking about.  This process is on our roadmap along with a 
bunch of other topics - hense my note concerning priorities.

Lots of reasons, not least are the broadening of the pool of expertise 
and the potential to leverage experience gained.
