The grouping is not really necessary for two policies. Also, any documentation
of the policies should go with the policies directly, not into a group
description.

Done.

We have just renamed public accounts to public sessions... :).

The order in which you arranged these items does not match the other policies.
Could you reorder so it's name, type, schema, supported_on, ...?

Done.
