what we CAN do is to depend on a specific (timestamped) snapshot
version - and of course for later Taverna upgrades depend on newer
snapshots.

We can also push on them to do an actual release. "Look, we're using
your stuff for real - and it works!"

The open provenance model is not needed for normal Taverna workbench
operation, right? Just for exporting? However I do guess if it works
we would want to include it in the GUI as well.. "Save this workflow
run's provenance" or something.

For that reason it might be better to keep it - although as a separate
module will be preferred as it should not be needed at all to simply
run the workflow. (For instance for a command line Taverna Engine -
again unless it includes a provenance export)
