Thanks all for the feedback! I've attempted to capture the following
feedback here
<https://shivankaul.com/draft-sahib-domain-verification-techniques/draft-sahib-domain-verification-techniques.html>
:


   1. Remove the naming of specific implementations
   2. Remove normative language
   3. Summarize recommendations up front

The audience here are providers. I think specific feedback about what
recommendations to include can be worked upon by the WG as a whole, once/if
we agree that the document is worth pursuing.

Does this help?
