Safe to say that in most parts of the US, the only likelihood of being able to even request 4W∆ would be for small loads in older overhead areas.

Con Ed [the electric utility in New York City] lists 2-phase and DC available {for older elevators} for as long as their serving equipment lasts, and then you gotta update. [Imagine somewhere there is an apartment building with 90-year-old tenants that has a motor-generator set in its basement…that probably won't restart after the next power outage.]
