Mixin Safe doesn't only support hardware wallets, also software wallets. Because from my opinion, Mixin Safe can already provides great security with Bitcoin Core or Mornin Key as the owner wallet, and I believe more and more software wallets will support Miniscript in the futuer.
Why do you choose Ledger hardware wallet as part of some packages when they have completely lost confidence by offering some very risky and unsafe possibilities?
The whole product of Mixin Safe is still in test phase, including the pricing packages. We included ledger a few months ago when it's the only hardware wallet that supported miniscript wallet policy.
