I agree.  I think being able to add things to Storyboard is great, and
as we've been using it more, we've done some of that.  But we've also
run into places where we found that we needed Storyboard to do some
things that were ultimately project-specific workflows.  So I think long
term we're going to have both things -- adding features that make sense
globally as well as ones that facilitate local configuration and

As an example, the "board" feature on storyboard can be really useful,
but we wanted to automate some of the movement between lanes.  Lanes are
arbitrary.  Rather than writing a new processing language to describe
that and incorporating that into Storyboard, we wrote a script to manage
one specific board using the Storyboard API.

The board is here: https://storyboard.openstack.org/#!/board/41

The script is here: http://git.openstack.org/cgit/openstack-infra/zuul/tree/tools/update-storyboard.py?h=feature/zuulv3

(Basically, that script automatically moves tasks between lanes based on
status according to the map defined on line 65, while still allowing
folks to manually move tasks between certain classes of lanes -- so a
task marked as 'todo' can be in either the 'New', 'Backlog', or 'Todo'

I'm imagining a future where we have lots of scripts like that (or maybe
a few framework scripts like Sean's, with configuration), and we run
those scripts in Infra but projects are responsible for their own
