There should be a way to modify login properties such as enable/disable, roles, etc.
With regards to Copy-SqlLogin which exists within the dbatools module, when setting up a new SQL Server it would be incredibly useful to be able to import all of the logins from another SQL Server that already exists (similar to sp_help_revlogin2). This should work for both SQL Server logins as well as Domain logins & groups.
