SOAP/WSDL has IDE support and various tooling because it would be almost unusable without it. Imagine doing SOAP entirely by hand, with a semi-complicated WSDL. It's a nightmare. Doing a RESTful service based on JSON data is not just not a nightmare, it's a breeze, with no need for any of the tooling you describe and with, in my opinion, absolutely no difference in API richness, interoperability, security, quality etc.
