PUBLISH: xpub Privacy Best Practices #writing

[ChristopherA]

Lead: TBD

This topic continues to haunt the bitcoin ecosystem with some proposed approaches that are likely bad long-term architecture.

Goal: define legacy best practices to avoid reuse of xpubs when creating multisigs for stateless wallets (for instance for single key signer), and higher standard for stateful wallets (Sparrow Wallet, Gordian SeedTool, etc.) but also start dialogue in community about architectures to do this right (probably xpub private commitments related to commitments also needed for FROST).
