I had a new hire on my team criticize the API we built for our product because we don't use put or patch, and we don't allow a GET and POST to share the same path. He said "it's not very RESTful"

I pointed him at HATEOAS and suggested if he wasn't familiar with it, he probably hasn't ever seen a truly RESTful API.

I don't think I convinced him that our approach is good (I'm not sure I am convinced either, but it works well enough for our purposes)

I do think I convinced him that "it doesn't correctly conform to a standard" isn't necessarily a useful critique , though. So that's a win.
