So, I think this particular request is actually looking for implementation of SQRL as a protocol within Bitwarden, rather than as an authentication method for one’s vault (in lieu of master password).
In that case, it is something of a duplicate of this from a few years ago, and could be merged with it: SQRL Identity
That said, I think making it also a method of identification and authentication into Bitwarden – a la Sign in using QR code without master password – in addition to SQRL identity storage for different sites is worth pursuing, particularly since many implementations already exist for client and server models.
