As already mentioned above, our scheme is not compatible with any other implementation, eg. Trezor or Keystone. The main reason is that our implementation is older than the finalised SLIP-39 standard, which is used by Trezor and Keystone.
So if I set up a social recovery option, and then AirGap wallet with all its services ceases to exist 5-10 years from now, how can I regain access to my funds if the scheme doesn't work with other hardware/software wallets? If you adopt the SSKR standard at one point in the future, does it affect all previously configured social recovery setups? Those created before your adoption of SSKR or whatever other model you decide to go for?
