The insistence on strict seriality and the proscription of feedback in phonological encoding place counterproductive limitations on the theory and WEAVER++ model. Parsimony cannot be stipulated as a property of the language system itself. Lifting the methodological prohibition on feedback would allow free exploration of its functionality in relation to the substantial content of this major research program.
