ENS names are going through an interesting phase. 

Original vision was one name everywhere, but L1 got too expensive so people have offchain ENS (farcaster) and L2 ENS (base names, world names). 

The natural progression seems to be towards multiple ENS namespaces - is this a net good thing?

Given that Basenames roll up to L1 (example: https://app.ens.domains/jrh3k5.base.eth) , is it necessarily 'multiple ENS namespaces', or merely a means of leveraging the existing infrastructure while reducing costs for the end user?
