Wago brand seem to have two types. Push in (PUSH WIRE® Connectors) and lever type (LEVER-NUTS® Splicing Connectors).
I just started to see the lever type discussed at a jobsite recently for use.
The push in type, although not Wago, were being proposed for the Hubble SnapConnect receptacles where the modular plug has the push in for the building wire branch circuit connection and is left for rough, and then the receptacle body get snapped onto the modular connector at finish by a helper.
We'll see if the place burns down.
