Very long term cold wallet with single passphrase generation

Make it easier to create a wallet by requiring only:

1. A good passphrase for it along with a Salt
2. A WarpWallet implementation to rebuild it.

Not BIP-39 with a passphrase and yet

“as secure as BIP39 although much more convenient and user friendly.” ―Bitcoin Glossary#WarpWallet

Interesting idea gone into great detail here.
