I don't think that specialized hardware is a security feature of Bitcoin, and definitely not one that was addressed or foreseen in the Bitcoin whitepaper (one IP one vote or one CPU one vote). In fact, it's quite easy to argue the opposite, that commodity hardware makes the decentralization/security of the network higher because anyone with extra space can farm. This is true today since Chia already has more full nodes than Bitcoin — you can run a full node off a Raspberry Pi :)
