I'm not sure what to think if this draft.

The way I read it some load balancer deployments that I currently have
are considered harmful. that may well be but they meet my needs so
there's a question of scope. not all edm devices sit between isp
customers and the internet.

If I don't have enough IPs to meet the requirement for a non-edm mapping
while fulfilling my other addressing needs with available resources I'm
going to overload, no matter what the draft says. If we would like to
provide advice that should be soundly ignored when necessary I'm not
sure what the value of the advice is.
