As a server admin I would like cPanel to allow users to specify new DNS record types by number
BIND and PowerDNS allow adding of arbitrary (not yet explicitly supported) DNS record types, using RFC 3597 syntax:
example.com.TYPE257\# 8 000569737375653B
Adding support for this to cPanel will allow early adopters to do sophisticated and progressive DNS configuration, without additional cPanel feature requests.
From my research, it appears that PowerDNS also supports RFC3597 syntax.
