Seems like the HTTP/2 protocol has been baked for so long, that whatever new methods are added, adoption will be very slow and only a small fraction of web APIs will expose those methods. In other words, aside from <1% of developers, no one will care. Also, graphQL seems to address many of the issues that manifest in the current form of GET. My bet will be that graphQL gets adopted more widely (and faster) than a new QUERY method.
