Not all of the rules are defensible, some of them are stupid or arbitrary. However, the NEC does represent the consensus standard, so it is reasonable to base one's expectations on it. My comments about multi-receptacle circuits were meant to provide some insight into the reason behind the NEC rule.

If for whatever reason you find it easier to install a 6-30R on a dedicated 20A circuit, it is not hard to document by putting a label on the receptacle face plate that says "20A".

Earlier in the thread you stated that the Clipper Creek LCS-20/LCS-20P "provide for only the following 4 plugs: NEMA 6-50, 14-50, L6-30, and 14-30". That is the entire reason I suggested putting a 6-30R on a 20A circuit. If the manufacturer's instructions don't say that you can change the cord on an appliance, doing so generally should be avoided, as it is at best an NEC gray area, probably it is prohibited.
