RFC 7942 does mention the direction of adding metadata to an RFC in the tools view:

"Later, the IETF Tools may support this
   functionality, e.g., by including such a link in the HTML file of the
   document, similar to the IPR link.”

It certainly is frustrating that different views of RFCs show different metadata, but if we had more formal repositories of implementation information, I think we’d want to be able to link to them.

A step can be figuring out how it would make sense present implementer information in a standard location and format, and we can figure out how to best tie it to documents next.

However, I'm not sure if putting this information in the RFC is the right approach. As you mentioned errata below, this are actually also not part of the RFC itself but only the metadata and it depends on the page that you look at if you see them or not. That a separate problem but I just wanted to underline that putting more information in the metadata might not be the right/only solution. I guess as a first step it would be nice get a better understand about how people usually find and use RFCs and maybe also how to redirect people to the right page then.

>> The genesis of what I am trying to affect is simple: We produce standards that describe protocols. As a protocol is being defined in an I-D, there are often implementers implementing the protocol or portions of it. These implementations are important, enough that RFC 7942 [1] recognizes the import of these implementations and exhorts I-D authors to create an"Implementation Section" to document these implementations. RFC 7942 also asks I-D authors to remove this section before the I-D becomes an RFC. My question is if there are implementations that are worthy of being mentioned in an "Implementation Section" of a I-D, why don't we preserve these implementations in an IETF repository and link the repository in the RFC.This way, new implementers of the protocol can quickly bootstrap their implementations, leading to a diversity of implementations, which can only be good for a protocol that is trying to find its footing.

>> When I talk to developers at companies and students at universities, if they have heard of IETF at all, it is mostly through knowing that someorganization called IETF produces these things called RFCs. That's it.Perhaps for them that is enough. And if you buy that argument, then the corollary is that we should do everything in our power to make sure that they have all of the information they need to implement the protocol from the RFC itself. Consider the errata we maintain in an RFC. Imagine instead of us providing the errata, we simply told implementers that it is out there, go find it. The errata is important, so we list it in an RFC.When a protocol is finding its footing, early implementations that allow other developers to understand its behaviour and derive their own implementations from it is also important. So why not formalize the process of archiving implementations that are worthy of being listed as per RFC 7942?
>> 
>> People have pointed out that we have WG pages, Wikis, datatrackers, and other such accoutrements for this purpose? WG pages, WG Wiki pages, datatrackers, all make sense to you and me. Many people will like to implement our protocols without burying themselves deep into IETF to know the difference between a WG page and datatracker. Their visibility into the IETF is through the RFC. So, put as much information in there that will make a developer productive.

However, I don't think that the issues raised are insurmountable.  The fact that an entire RFC [1] was standardizes around the issue leads credence to the fact that it is an issue deserving some sustained attention.
