Ok, I can live with doing this in a second round as this feature is quite under the hoods. Could you open another issue to track this?

I think this PR is basically good but would love to skim over it one more time. But I think it's safe for you to rebase #119 on top of this and move forward with that.

Yeah, that'd be nice. The more real-world feedback we get, the better.
