These are orthogonal things, absolutely. When you run Samba as a file
server, you are not limited by SMBv1. Your user and group information
can come from multiple sources, regardless how you are joined to domain
or not joined. SMB protocol version is irrelevant because the checks we
do for netgroups membership happen when we check access to shares, not
when we choose which protocol to use.

This is not always about 'AD member workstation' case. Samba does
support more use cases and they aren't being removed at all.
