Key problem ENS domains are only available on Ethereum mainnet where gas fees are really high. There are NFT domains as Unstoppable Domains which you pay only once and your domain NFT is yours forever, but UD have not taken much popularity as ENS.

Other think to know you can use your .XYZ domain on ethereum as ENS.

Nah, I registered an ENS domain for 10 years last week for a total of $80. That's cheaper than many traditional domain names. Gas wasn't even that low either.
