Yes, there is data to back up.
No, it doesn’t require a seed from every device.
This has been the value proposition of Casa for over five years, it’s not some obscure theoretical concept. It’s surprising how misunderstood multisig still is today, especially within the bitcoin dev community.
Yeah if you want a trusted 3rd party in your multisig to back it up then that works. However you have massive trade offs for that.

I provided an example of a product that’s been on the market for half a decade to illustrate the absurdity of the claim that multisig is useless as a redundancy solution.
This redundancy+security model is built on Bitcoin primitives. Nothing about it requires a third party.
Regardless, for 99% of the population, granting a third party access to view their transactions in exchange for self custody of assets (and the possibility of having them assist in disaster recovery), is a huge improvement over giving up custody to a third party, which is the default in most cases (fiat banking/investments, Bitcoin held on exchanges).
