I know it's not design for it. I'm just seeing what's possible.
Overkill... well.. Would be cool to have a 100% air gapped solution where neither the keystore nor the computer has touched the internet (and still make it a 2min job to use it).
And yeah, I could just use regular computers without the HW wallets, but then the key is exposed to Linux and electrum with all it's unknown dependencies. So just in case it ever got online the key is still safe.
Coldcard could simplify tho... But all my HW wallets are from different vendors, so I like to have options
