I think the lock is useful. The cable is heavy and, in some situations,
might pull itself out. Or might jiggle loose if someone steps on the
cable.
The electrical interconnect could be solved without a lock. Just have
the signal pin be a bit shorter than the main conductor pins so that, if
not plugged all the way in, the signal drops.

The lock is to prevent arching when you disconnect

I have never understood why the NEC _requires_ an EV charging plug be
"locking".
It makes no sense.
If you drive away (or the vehicle somehow rolls, is towed, or moves
away) the plug should simply come out.
As it is now, the locking plug won't give, so the cord breaks, or
worse, the charger rips from the wall, damaging the fixed wiring.
The plug should not be _required_ to lock into place. It would be far
safer to simply have the plug come out when the vehicle moves and the
cord is strained.
