No kidding. The problem isn't with DNS server software like BIND and NSD, 
which are updated regularly.  The problem is the Web Crudware(tm) that 
most people use to manage their zones.

See https://datatracker.ietf.org/doc/draft-levine-dnsextlang/

I think I have funding to revise and implement this, by the way.
