Hey man I have also been pondering this issue. I have scoured the internet and found no definitive info as to how I can recover my hidden wallets should trezor go out of business. Ledger offers just ONE hidden wallet. Starting to think that my 6 hidden wallets are just a possible liability down the road. Did you get any insight on this?
I understand that my coins are safe if the Trezor company ceases to exist.
But what about my staked Solana, ETH and ADA… how could I stop staking and withdraw them when my Trezor wallet or Trezor Suite is no longer available?
