PS audio why no true 20 amp HC PC for power regenerator?

With the release of the highly regarded p20, p15 and p12 regenerators why hasn’t a true high current power cord dedicated solely to be used to power these New products been design. There’s no 20 amp cord available only 15 amp. I’ve read from many highly acclaimed reviewers stating you should buy a PC from the manufacturer of the Power cond, regenerator because they design their products with their own HC powercords and they work best when using their own cables.

What components are in your system?
