We have this commented-out chunk of code now which was originally buggy and is now just nonfunctional.

For now, the core edit types don't always require CAN_EDIT (e.g., subscribe, comment, add edges), except for editing the edit policy itself, which always does. Add a supplemental capability check there and let everything else go through with CAN_VIEW. We can buff the policy checks on application editors over time, they all require appropriate capabilities to get to in the first place anyway.

Created and edited some tasks without getting overwhelmed with policy exceptions.
