They are coming. Keep in mind RAML 1.0 was JUST released a couple days ago, and various tools, most notably parsers in different languages, are in the works. NodeJS and Java I believe will be available soon, along with GoLang, Python, and a few others. Once the RAML 1.0 parsers are ready for consumption, you will start to see a lot more generators of all sorts. A lot of the reason RAML seems to be behind other tools like Swagger and such is because RAML 1.0 took a bit longer to get released, but when you see the capabilities of RAML 1.0, you will appreciate the efforts that went in to making it as good as it is. You just have to be a little more patient for the parsers and generators.
