Yeah, this was discussed last time. I disagree. Every year, dozens of new Bitcoin-related products are launched with the hope of attracting enough users to support continued development, and dozens of other Bitcoin-related products from previous years are discontinued because they failed to attract enough paying/donating users. The risk of a new thing failing to gain traction and becoming unsupported is an ordinary risk in this industry (and probably every innovating industry).
This applies to existing long-term Bitcoin security products. Anyone who uses Casa, Unchained, Liana, or other self-custody-with-backup-signers multisig products must prepare for the possibility that parts of the product suddenly become unavailable and that the remaining parts fail over time, necessitating a funds movement. A transitory soft fork is similar, except that it’s extremely unlikely to become unavailable prematurely.
