Some AHJs, btw, are just outright ignoring the code and demanding EV chargers be counted at 100%, essentially on top of 220.83 or .82. On the one hand, I can see the point of that, since unlike other loads EV charging usually draws near full nameplate for hours without cycling. On the other hand, it's incentivized to be used at off peak times, not coincident with the rest of the customers peak load.
That is not available from all utilities across the country.

This reminds me of the sticker on combination panels I purchased, "This spot is reserved for solar only". Then, I would be working a service call, and that spot had breakers not serving a solar circuit. What should I do then ?

Why does it remind you of that?

That sticker is kind of BS but it makes it easier for the installer to comply with the 'opposite end' part of the 120% rule. It's also a signal to inspectors on new homes that the panel meets solar ready requirements.

How do you get to read the PI's before they are released as part of the first draft report? Are you on the committees or something?
