I've always considered the HW wallet's highest purpose to securely create private keys which should really be, as you point out, stored as seed words in physical medium. For me, cold storage is HWW agnostic ultimately.

Yeah, this.
Steel washers remain undefeated.
I can see having a HWW if its a "warm" wallet and you sometimes need to sign a tx.
But nothing comes out of my cold storage so I just have a watch only wallet and the seed on steel.
That’s my thinking. Properly generate good entropy keys and keep them analogue securely forever.
