A bank of 50 NEMA 5-20 outlets is tiny a fraction of the cost of installing 4 EVSEs. So yet, you could get far more of them.
.
Am I mistaken in thinking that this would be a 1,000 Amp service connection ?

I agree btw with your larger point that L1 has a smart place to play in EV charging infrastructure at places like airports; and perhaps workplaces.

A 400A commercial service connection at 208Y/120 volts 3-phase would work with some extra capacity for lighting.

Well then, I still have not grasped basic power calcs. Why is your solution not 400*208 watts ?

The long term lot I use has 10-15 spaces that have 5-20s that turn on at night plus a similar number of Tesla wall connectors. You simply park there and don't worry about the length of time. They also have a small number of L2s in their valet lot. The OP needs to check with the lot that they are using, as the site owner will set the rules, not Chargepoint. If they have plenty of capacity, then parking long term isn't a problem.

Tying up a charger for duration seems wasteful . I know DFW has high capacity chargers L3 in every direction outside the airport. Spend $6, charge up for 30 mins and you are good to go.
