A rotating tank is a tank that rotates. If it does not rotate it is not (used as) a rotating tank. Where have I missed the point? And the point was that a MOD54/Paterson tank can be used to stand develop six sheets of film which a rotating tank (obviously really) cannot. Additionally the use of a tray to stand develop a single sheet of film for maybe an hour also seems impractical given the oxidation, but not impossible, although you can try it, not me.
My original comment was perhaps slightly out of context because rotating tanks hadn't already been mentioned (but had in other threads) with discussion about how little chemistry is used developing 4x5 film, but there are other techniques available using a MOD54. But I did specifically say rotating, and did not allude to the generic use to which a Jobo tank can be put to.
