Thanks to the authors for a clear and important document.

From an INT perspective, I didn’t find any areas of concern. The example IP
addresses used are all v6, so that should make our ADs happy! :) Broadly, the
main relevance for INT here is that the privacy mechanism of obfuscating the
SNI works when at least several different names can be accessed via a common
address or set of addresses. The descriptions of this behavior looked correct.
