I am the founder of Starlight Charging[1]. We are working on crazy-low-cost L2 chargers for multifamily apartments. Plug-and-charge is a sine-qua-non for us.
One still major unsolved problem is the lack of agreement on a standard for payment/powerline communication from the EVSE to the vehicle. OCPP 2.0.1 and ISO 15118 is supposed to bring "Plug and Charge" capabilities -- this, in theory, would allow drivers to simply pull up to a station, plug in, and charging start right away. i.e. No more fiddling with multiple different manufacturer's apps, no more being SOL if your phone battery is dead.
While we're seeing agreement on the physical standard for the shape and size of the conductors, there's still progress to be made on the protocol between vehicles and charger. Tesla refuses to implement OCPP because they have a great walled garden right now and don't want to release the stranglehold on the payments.
