It's a nice idea but doesn't quite allow the same level of repeatability. Most
taverna workflows need updating periodically, as the services go offline or
change their interfaces. Even if they don't, they return different results as
the implementation changes. 

Ultimately, you need to store more than the workflow to allow any degree of
repeatability. Still, it would be a good step forward which is no bad thing.
