Process editors for a sub-group used to be independent of the parent group. Sub-group permissions now inherit Process Editors from the parent group, which can be contrary to required functionality. To manage this requires an increase in the number of subgroups with all processes in subgroups to enable control at each level, a greater admin overhead.

Thanks for the feedback. This isn't on our current roadmap to change, so for now we'll open this for voting and monitor interest from other clients.
