all your addresses seems super relevant and easy to change the 24+ character string into something more recognizable like cryptocat.zil
If ZIL team will ever manage to get the main wallet providers - Electrum, mycellium, samourai, trezor, ledger, and so on (the list may not be great, but it proves the point) - recognize and use .zil addresses then yes, .zil will become something relevant. Else it'll just stay as an interesting idea.
