Nope. Retarded people need simple.
I can use whatever design I want.
That's the beauty of bitcoin. You don't design anything for everyone. Everyone can use whatever design they want.
I'm saying this is a non existent problem. Basically any hw wallet will serve 80% of users and the 20% should not design their custody based on podcast ads anyway and will invest time to do it right, because it matters.
