When most people refer to REST APIs, they really mean "HTTP APIs". I really don't think we should reach for GraphQL just because of the ideological notion of daring to not adhere 100% to REST.
If you’re going to abandon REST design principles, then you’ll eventually end up with something that pretty much does what GraphQL does. At that stage why not just adopt a more fit-for-purpose set of design principles?
Keep in mind that I’m only really advocating for it as a query language for HTTP APIs (which as a side benefit has some nice existing tooling which you may or may not find useful).
