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?

This was part of my thesis for Everyname, which aggregated and resolved all onchain names associated with any wallet address (both EVM and not)

Our thinking was that usernames will eventually be onchain, and that we will likely have app specific or context specific onchain usernames which is now starting to playout

In web2 the canonical identifier was typically email, in web3 its the wallet address — apps will most likely offer both their own usernames and the option to use a universal name (.eth)

Basically what Warpcast is already doing — its neither good nor bad, as long as the canonical identifier (wallet address) remains, and one of the primary reasons I'm on the fence about apps using embedded wallets

Do you really see wallet addresses replacing email as canonical id?

Seems to me email is too simple + entrenched to replace, but I could be wrong.
