ACL priority

I assume it is related to this issue. Will this example be possible if ACL would have priority:

1. OG module is enabled and it's content access is enabled. Priority = 0
2. ACL priority = 1
3. Content access (which implements the ACL) priority = 2

I'm expecting two things:
* that only users from a group, the are also in the ACL and with the correct Role will be able to access the node.
* The node permissions (view, update, delete) will be defined by CA according to Role, not by the ACL - I'm thinking about this since I'd like to implement OG subgroups using ACL
