Simple resistor signaling wouldn’t work for current sharing; two EVSEs with a single 40A supply [32A continuous] can advertise 32A if only one is in use and switch to 16A if both are in use. (Same concept extends to a larger pool of EVSEs which can limit to a max total current across the pool.)

Ah, okay, that is fancier than just advertising a fixed max current.
