There are good arguments that if you were designing this from scratch it would still make sense to separate GET and QUERY. GET are things addressable purely by URI. QUERY are things that need HTML forms or JS to initiate (but optionally may return GET addressable URLs for future requests). Similarly there are good arguments that if you were designing this from scratch it would make sense to still separate QUERY and POST. To some extent they mean very different things: "search" versus "create"/"do". Some of that is a modern expectation from years of mapping the common "CRUD" concepts to "REST": POST ~= Create; GET ~= Read; PUT ~= Update; DELETE == Delete. But that's a lens that's still useful in designing the thing from scratch even if it wasn't necessarily in mind when HTTP was first designed (especially given the different verbs in HTTP terminology).
