Initially, there was a lot interest and energy in reducing the flooding 
overhead in dense drafts. Now, it seems the interest and energy has waned. IMO, 
this draft contains some very valuable extensions to the IGPs. I discussed this 
with the editors and one suggestion was to go ahead and publish the draft as 
“Experimental”. However, before doing this I’d like to get the WG’s opinion on 
making it experimental rather standards track. Additionally, I know there were 
some prototype implementations. Have any of those been productized?

<tp>
The trouble with experimental is what happens next?  Does it stay experimental 
for ever or is there some assessment at some point when it becomes Standards 
Track?  What are the criteria?  I am not aware of an RFC describing such a 
process and the IPPM WG seemed uncertain what to do with RFC8321 and RFC8889 
when such an issue arose.

The shepherd report for 8321 said
'the measurement utility of this extension still is to be demonstrated at a 
variety of scales
   in a plurality of network conditions'
as the justification for experimental but did not state how that might later be 
demonstrated.
