Fair enough. However a long-dead draft that got little traction then  
or since hardly inspires confidence that the concept behind it is  
still worth pursuing today. If others disagree, feel free to exhume  
the draft and have another run at the issue.

I wonder too if anyone deploying these SRV records has done any  
research on how often they're looked up and the results are acted on?  
It would be interesting to get some raw data on the number of SRV- 
aware whois clients that are out there, how often they get used and  
how many lookups they generate.

It's just an example of another ad-hoc idea for finding whois servers  
that didn't catch on.

There doesn't seem to be much point in promoting these schemes. Or  
adding to the confusion by having "competing" incompatible and  
inconsistent ways to try to do the same thing. To put it bluntly, none  
of these ideas have been widely adopted by TLD registries even though  
they required negligible effort. The registries have voted with their  
feet. The idea is dead. Sorry.

Possibly. Though since that draft died 6-7 years ago, nobody's yet  
showed an interest in reviving it and few registries are using the  
scheme, I think that tells its own story. As I said earlier, it  
doesn't seem likely anyone has the appetite or energy to work on this.  
Or persuade registries to adopt it. If they did, something would have  
happened long before now. It hasn't. QED.
