To my mind that is as good a reason as to leave the rule as simple as is possible and just say three points of contact with the ground i.e. two feet and one knee.
As to any bleats about unfair advantage - well if it is left simple then it is up to the individual to find what works best for them - much the same as how the sitting position varies from person to person.
BTW I am a former FT shooter.
