I agree a draft describing the places where DNS evaluators
should set limits would be a good idea.

I am considerably less enthusastic about specific limits, since
the use of the DNS has evolved a lot and some things that may
bave seemed excessive back in the day are now routine.

The obvious example is CNAME chains. In 1034/1035 the only use
contemplated for CNAME was temporary forwarding when a host name
changed, and for that use, chained CNAMEs made no sense. Now they
delegate authority to different points of control in many different
ways. For applications like CDNs, you need two or three link CNAME
chains and nobody appears to find that a problem.

R's,
John
