A client paying your invoice should not get a free tour of your wallet history. Reuse a public address for work, and a simple payment can reveal other transfers tied to that address. That is a practical reason to care about @Americanfort_io Its FortressNames design lets compatible wallets resolve a readable name to transaction-specific receiving addresses, aiming to reduce the public link between your name and your wallet activity. The current wallet is still in beta, so this is a direction to watch, not something I would call proven for everyday business payments yet. For me, the useful test is simple: can someone get paid, find the payment and keep unrelated activity private without extra work? That would give people a reason to use it again.
