Agreed, which is we've consistently advised registrars and customers to use EPP <domain:check> (rather than the Whois) to implement availability checks. The general problem with services such as the Whois or RDAP in this context is that these services are only suitable for telling which domains are definitely *unavailable*, but not which ones are available. There are plenty of cases in which a <domain:check> correctly yields avail="false" but Whois or RDAP services return "not found" results, which are easily misinterpreted as "domain available". Whois/RDAP are services for obtaining information about existing domains, not about availability. I believe that any attempt to add availability check capability to these services violates the "separation of concerns" principle.
