I actually agree with you guys, those figures represent the far end of PM customization and I definitely would not like to see official sets with that much detail. Nor would I do any such myself. (My own style is ultraconservative - no alterations of parts, no unofficial parts.)
BUT...I greatly appreciate creative work in any style and I feel that this sort of extreme custom enriches the Playmoworld. By showing what is possible and what aspects of the imagination PM inspires, customs like these make the hobby greater for everyone.
Just my opinion! What can I say I love all customs. MOAR
