Disable attribute filtering

His concern is the need to enumerate the attributes. It's easy to write a policy that is always active, but the rule to release an attribute is expressed based on the attribute ID, there's no wildcard syntax like the SP has to say apply this rule to every attribute.

At least I don't think there is, but it is possible to do some weird stuff in the filter by mixing in Policy rules in place of Matchers so it's possible there's a way.

Even if it's "needed" I can definitely say it will probably be implemented directly by porting the wildcard feature over because the SP will need it.
