No, because they're not really broken. I think this is fairly clear:

Based on what we have learned during this incident, we have reverted the CNAME re-ordering and do not intend to change the order in the future.

To prevent any future incidents or confusion, we have written a proposal in the form of an Internet-Draft to be discussed at the IETF.

That is, explicitly documenting the "broken" behaviour as permitted.
