 >> I agree. In our case, and I am sure the same holds for many other 
CAs, there are many situations where the Applicant's ownership of a 
domain can be ascertained beyond any reasonable doubt by examining WHOIS 
records and cross-checking with the Applicant over a reliable 
communication channel or possibly face-to-face (in front of a CA 
salesperson), without any need to technically interact with the domain's 
HTTP server or DNS server or to send emails to the domain's 
administrator. The fact (which is unquestionable) that in certain 
countries and/or with certain request channels the above is not always 
true, does not seem a good reason to abolish this method.
