You must validate your keys, as I know it is mandatory and that is why we have delay because a lot of people didn't validate their keys
I really don't want to. My keys have been accepted, I have stored them offline. I don't see the reason to validate the keys. It doesn't feel right to me...
How can you know your keys accepted if you didn't validated them?
Once you completed the exchange a window popped with the address and passphrase. It gives you the option to download the credentials to a text file and afterwards you close the dialog box by "accepting" or basically saying that you've recorded the pass phrase.
And this is why we can't have nice things.
