The problem is that user at ai is not globally unique. MIT users will have problems talk to user at ai when "ai" means Anguilla. The is a current security issue. If / when MIT stop using ai.mit.edu, "user at ai" will not longer mean user at ai.mit.edu. This will mean that any configuration file that has "user at ai" will now, suddenly, get a different meaning. This is a latent security issue.
If by "latent" you mean "so obscure that in the ten years that there's been A and MX records at TLDs nobody's been affected" I guess I agree.
