With a secure enclave of some kind, there could conceivably be a three attempt limit before the temporary key associated with the pin is deleted, and full pass phrase is required. In such a setup pin might make sense. As it is - I'm not sure if pin makes sense even if there's user demand? Then again I do use biometric unlock - and that's not really great either. At least the bitwarden installs are behind fde (macOS) - and possibly (?) file based encryption (Android 13+).
