I'd argue that RFC 1034 isn't absolutely clear on this topic, see
Also, when you say "not followed", would this only prevent actively chasing
the CNAME target or would it also prevent data already present in the cache
from being added to the response?
In any case, any optimization should not be seen as an encouragement to
use qtype ANY in applications -- for anything else but debugging.
