In PABS defense, I did ask "which, if any, of the following
asymmetric, non-PB-leadend treble dodging major methods have
extensions to a higher stage (not necessarily royal)? CC-algorithm or
the more fecund PABS-algorithm, as you choose". I think that was
asking a question for which G(B)5 would disqualify potential
extensions. That is, I was spcifically asking about what happens when
the algorithms currently under discussion are applied, not what is a
suitable extension (whatever that means, if anything).

And I thank him for his clear answer, regarding what his informed
intuition tells him.
