Yes, it is just relying on that.

A question of you as a chair: does the wg you chair publish documents
based on current specs (or at the very least based on  changes that are
going to happen in the near term as a result of *existing and proven
consensus*), or does spring ship documents that implicitly betting on
changes that have no consensus?

The former is how I expect WGs to operate. The later shows a clear path
to a huge pile of documents stuck at IESG review, simply because so
later in the process folks found out that the document turns out to
violate existing specs. With the risk of an AD pressing "YES", and hence
IETF has been circumvented.
