While the extension can be briefly specified, its implementation seems excessively costly to me. To make the availability check work as described, the RDAP server would have to be equipped with access to the same (potentially complex) rule/policy engine that governs the principal availability of domains in the SRS. Such an engine is usually not just defined by a static configuration, but by a dynamic system involving database content (such as reserved names list), launch phase setups etc. I'd assume that many registry systems are designed with Whois/RDAP servers being standalone applications, with their own database, connected to the main SRS via a lightweight feed mechanism transporting information about existing objects. Implementing the availability check in such a setup would require that feed not only to carry repository objects, but also all data making up the SRS's rule/policy engine. That's a lot of effort to add a functionality that (at least in my point of view) is out of scope of RDAP.
