I am pretty sure we should rename the recently added ControlGroupNFTSet= unit file setting before the 252 release. The "ControlGroup" reference should be removed from the name. Unless a field is directly exposing ac group property (e.g. ControlGroupPath= or ControlGroupId=) in most ways control groups are an implementation detail for us. One that is worth mentioning in the man page, but I am sure we should not include in settings names, because it's irrelevant for the purpose of this setting.

Moreover, it would then be more symmetric with the NFTSet= setting in .network settings, which is also just called NFTSet= and not AddressNFTSet= or so.
