This is a great idea. Sorry it took so long to respond. I spent a couple hours on workflow issues today, adding a new action and a default configuration. I also made a type available for contributions posted in the contrib directory called "Workflow Configuration." My recommendation would be to post these sorts of configurations as contributions so others can find them easier down the road, and we'd be sure to contact you if we wanted to fold any into core.

I'll be writing documentation on workflow tomorrow, and I'll be sure to point out that configurations may be imported/exported using the Workflow UI.

Thanks for the post!
