that's my view of the def'n of "interoperability" as it applies here.

yes and no. yes, name server implementors should compete to build the
best possible rate limiting. but also no, it's necessary for large
multi-server authority operators to have the same kind of rate limiting
on all of their servers, and they want to be able to use more than one
rdns vendor to avoid monoclonal problems like packet-of-death

yes, even if it's an FYI or BCP document rather than a STD.
