Re: [spring] Proposed policy on reporting implementation and interoperability

[Suresh Krishnan <[e-mail]>]

Hi Joel,
 I think it is a great idea to keep track of the implementation and interop status of the Standards Track work that spring produces. My thoughts are very much in line with what Adrian said below in that I would certainly not like this potentially stale, out-of-date and misleading information to be included in a published RFC. I have a couple of additional points to make:

* If the WG has consensus to continuously track implementations, I think one potential way to  do so would be a WG wiki which could be referenced in the published RFC.
* Even as the draft is making its way through the IETF process it might be important to keep track of the freshness of the implementation data and this requires recording such info. I had brought this up during the IESG eval of the draft that became RFC7942 
(https://datatracker.ietf.org/doc/rfc7942/ballot/#draft-sheffer-rfc6982bis_suresh-krishnan) but did not push it since the goal of RFC7942 was not to continuously track implementations. Here are the two items I had proposed:

1) A datestamp for each implementation to denote when the implementation was added to the draft or was last updated (to determine freshness) 
2) Draft version number that was implemented (as drafts can change significantly during the wg process)

Thanks
Suresh

I think this changes the purpose of collecting the information and making it public. It moves from being information that is valuable for assessing the status of the work, to something that verges on a marketing statement. In particular, companies that are able to get into the RFC reporting their implementations will, forever, be named in the RFC as known implementations, while other companies (perhaps those who waited for consensus before implementing) will be excluded. This seems wrong, and while the text you propose to include might make it clear that it is just a snapshot at the time of publication, it will still be there as a public record. The IETF is not a proxy marketing machine, and this information is not useful for the technical content of the RFC.

If the WG agrees, we would like to institute and post on the WG wiki the following policy.  The period for discussion and comment runs until 9-Sept-2022, to allow for folks who are on summer break:

Authors are asked to collect information about implementations and include what they can find out when that information is available for public disclosure.  Documents will not be blocked from publication if the authors fill in the section as "none report" when they have made an effort to get information and not been able to.

This may include a reference to longer and more detailed testing reports available elsewhere.  If there are no reports of interoperability tests, then the section MUST state that no such reports were received.
