Rule Selection:
Laurent: We shall say that the Rule offering the best compression shall be selected.
Ana: RFC8724 leaves to the implementation the freedom to choose the Rule it prefers. Your example should be avoided.
IM: Yes, but there is still a probability based on the implementation choice that the modified rule is chosen. Therefore, the attack vector still exists, so the example shall not be avoided.
Rule Database:
Ana: The concept is present in the archi draft but it is not cited anywhere in the RFC. Shall we say this is rather a Registry?
Ivan: Shall we ask in the ML to reach a consensus on this terminology?
