CH/TXT/VERSION.SERVER queries

[Anand Buddhdev]

Hi folks (especially BIND developers),

Apologies if this has been discussed and answered before. I just noticed 
that BIND doesn't respond to CH/TXT/VERSION.SERVER queries. It only 
responds to ID.SERVER.

Other name servers, such as Knot DNS, NSD, Verisign's ATLAS name server, 
Quad9's and Cloudflare's public resolvers, respond to VERSION.SERVER 
queries.

So what's the reason for BIND not responding to VERSION.SERVER queries? 
It seems like an anomaly or oversight.

Regards,
Anand
