I'm not disagreeing with any of that. But on Discogs they have to be explicitly labelled EPs from a direct source (ie not a distributor / store) before they can be tagged as it.

Honestly, try not to get too hung up on Discogs stuff. I know how tempting it is to try and make it look neat and tidy and more logical, but fundamentally that isn't really the point of Discogs - it just exists to document what exists in the most accurate way possible. Truth is, with a series of releases like this, terms like album, EP, etc. are intentionally being blurred and made irrelevant. Don't worry about them too much.
