it,s simple really : Oda needs power up with sanji so he go creative with raid suit for enhance power ,durability and invisibility
but people in social media Especially SJW Turds and FEMINAZI ridicule sanji because he use it to peeping woman bath.
oda realized lots of fans hate Rs so he dicide to power up sanji by gene modification using RS as "tool for arousing" sanji genes so after rs do his job oda destroyed it

kinda sucks really but why destroyed upgrade after get it? i sure oda realized lots of ppl ridicule sanji especially in twitter.
