To help bolster your claim, the last part of that resolution (3600) coincides with what we would refer to as 720p, 900p, 1080p etc., and it is only evenly divided by 720 and 900, by 5 and 4 respectively, while dividing by 1080 does not produce a whole number. On the flip side, all of the seemingly built from the ground up games, Splatoon 2, Arms, and even Mariokart all were shown originally as running at a max of 720p, only to be released at 1080p. Well maybe Mariokart wasn't shown originally at 1080, but it does run at that resolution docked.
