Why doesn't NFTs use something like IPFS so that if the centralized entity goes down, the NFT does not?

Is it because these decentralized file systems are no where near as performant as something like AWS S3 and can't be used to quickly load NFTs?

GameStop's NFT Marketplace uses IPFS: https://nft.gamestop.com/

For example see https://lexplorer.io/nfts/0xdcf8ff6b4de163873066118a8eeec9e6...

- MetaData URL ipfs://QmbpB8hWvDuvtyHRDPQSMwg4EGr8AqbKH1Vq3eNknZew9p

- Image URL ipfs://QmNq8T2e4DGiDuyHEgBM9WEpfUTE8TFuXAkTWVVQ8vbFc5

- Animation URL ipfs://QmYBdBXzCXoYyr1vKPQJGKbb97P2ypPpA5jAL9emiB6EcE

Also, GameStop has a domain configured a node to access IPFS as well to appear on Web2 (but unfortunately the www subdomain prefix is required and the domain is not configured to work without it)

NFT metadata is stored in a centralized service,like S3,because it is more mature and cheap. The decentralized storage, like IPFS or arweave,is also an option.
