Creating NFT on Optimism

I'm working on a NFT collection on Optimism. Layer 2 has much lower fees than main net. I'm surprised NFT has not taken off on layer 2 yet. There are a lot of NFT being released on Polygon but that's not true L2. I'm hoping NFTs will take off on layer 2 once Opensea supports them. Anyone has any thoughts on NFTs on layer 2?
