Support for CNAME at the zone root

The blog post Introducing CNAME Flattening: RFC-Compliant CNAMEs at a Domain's Root by CloudFlare describes a technique for having a CNAME record on the root of a zone. This feature is very powerfull for cloud services providing service records on the root of their service zone. Having a feature like this in Knot would allow records like:

$ORIGIN myservice.net.
@    IN     CNAME    mycloudservice.net.

What do others think about this feature supported by Knot? Or a similar form to have the possibility for CNAMEs at the root, like ALIAS record type as DNSimple is doing it?
