soap was a really good interoperability protocol for adding kilobytes of overhead to simple text based rest rpc where interoperability was defined as being able to interoperate with clients and servers from the exact same software environment.
trying to get perl to talk to windows or windows to talk to java or java to talk to perl never really worked at all.
but wsdl was like this tempting thing. self describing services! (that only worked when you had a full definition of the service on the client side anyhow)
i'd take a wild bet that this stuff at amazon grew out of frustration with soap a long time ago...
edit: read new replies to thread. this is new as of 2018. soap was circa 2002. ah, well.
