I don't think it's utility is in memorizing, very few people will do that and it's likely very unsafe to do that, even if technically possible.

The utility I believe is the ease for secure air-gapped transmission of the secret for backing up or restoring in another application. It's a lot more straight forward to backup the secret by writing down a series of words that it is writing down a series of letters and prone to mistakes. It's a less technical option that many people will understand.

As far as it being unencrypted, an additional password can be added to the words as the last piece of entropy for additional security.

In my opinion, use should be encouraged with Nostr apps.
