We discussed it a few meetings ago and felt that it overly complicated
the schema for the amount of gain in the short/medium term.
For example, insecure RFIO and DCAP are published without restrictions,
and in practice this is not a real problem today.
Since we want to converge on 2.0 ASAP, we felt such enhancements were
better considered for 2.1.  Would that be OK for you?
Thanks,
