Core intentionally doesn't invent a special "paper-encryption" scheme or mnemonic. If you want a physical backup you have to add the protection yourself.
Core devs generally recommend encrypting the wallet (encryptwallet), then keep multiple offline copies of the encrypted wallet.dat in different places (USB/offline disk, etc.).

I am not sure about the "intentional" part. Perhaps they've found some ways to do it manually that aren't standardized and that's why they're not featured in Bitcoin Core.

I am not a fan of digital backups. If you have 3 media in which you store your wallet.dat, chances are you'll be ok, but I prefer trusting paper.

The problem is, that the easiest way I 've found so far for doing a proper backup is the following:

1. Export the private descriptors in a JSON file.
2. GPG-encrypt the json file.
3. Print the encrypted cipher.

The cipher though looks like this:

Code:

Easy to print, but very difficult to write down in order to decrypt it.

So, getting a QR code out of this is, perhaps, easier.

Anyway, I guess I am asking primarily because I want to see if anyone has a good way to backup a Bitcoin Core wallet on a physical medium (paper ideally).
