Well, that's certainly a worthy discussion and it would be great to get the list 
engaged on it.

And indeed, I'd guess that ++ and Full Standard ought to correlate highly.

There is an underlying question that I'd suggest you post an answer to:

       Why should the two be linked?

       What benefit derives?

       On what basis would it make sense for them /not/ to be linked?

For example, the standards label is a formal, political process.  It's rare and 
difficult to get to Full.  (The YAM wg has embarked on a test of this, and the 
experience so far is not pretty.)

The wiki is intended as an extremely informal and flexible process.

The difference between these is fundamental.

For Draft it is only required to talk about /two/ implementations.

Full Standard pretty much /is/ in terms of usage.

If your concern is 'instance' vs. 'implementation', that's to keep the column 
narrower.  And no, I'm not kidding.  If there is a real indication of community 
misunderstanding, then the disparity is important.  However the idea that the 
community cannot tolerate synonyms -- especially given how loose people tend to 
be with their vocabulary -- should be documented.

If your concern is something else, please elucidate.

What do you believe is established terminology that achieves the same purpose as 
the Adoption column is trying to serve?

That's an inclination that has intuitive appeal.

However we need to be careful that it does not produce slavish adherence that 
undermines actual utility.  Since the standards process and the wiki are not 
identical instruments, it's entirely possible they need disparate terminology.

I'm not saying I'm sure they do, but merely that the decision needs to be made 
carefully?

Again, that has intuitive appeal.  Note, however, that essentially everyone but 
serious, longer-term IETF geeks have no feel for the standards levels at all. 
So I am not sure I see how the link makes anything intuitive for the larger 
community.  (FWIW, I'm not happy about that observation, but I think it's 
factually correct.)

You still have not answered the underlying question I've asked a couple of times:

    Implementation is interesting only for standards that have not been very 
successfull.  As such it is a secondary measure.

    Why elevate it to primary?

David, you keep wanting to turn the wiki into an extension of formal processes, 
when it is carefully designed to be quite different from it.

We have extensive community assessment that the formal process is problematic in 
effort and vagaries.  The wiki is designed to be informal, simple and direct. 
It asks only one question:  Did an expensive community effort succeed?

For each change you suggest, please think hard about the value proposition of 
the change and look for ways that an otherwise-reasonable value proposition 
might actually /not/ be true.
