I think it's awesome that we have multiple multisig wallets / multisig service providers in Bitcoin. In the past few years, great progress has been made in terms of inter-operability (PSBTs, descriptors, etc.), so that the users don't have to be "locked in" to any particular wallet / vendor. This diversity of choices is great for the end users, and directly contribute to strengthening the entire Bitcoin ecosystem.

If anything, I think multisig is significantly underinvested, especially when compared to something like the Lightning Network. I would love to see more multisig projects / more experimentation in the future.
