The obvious solution is underrating - just like a 1 TB SSD actually has more than 1TB of "raw storage" available internally. What is a 100% battery today will be sold as an 80% capacity tomorrow, with 20% "overage" available for wear.

That’s fine as long as the battery ends up having 80% real capacity after 1000 cycles and maybe Apple is also transparent about how.
A bigger issue which I don’t know if the law covers is with the other battery specs. An 80% battery that can’t handle any spikes (low power mode) is useless.
Isn't the most obvious end game just (if using the same packaging) some note on a spec sheet of "12 hours screen on time (10 hours in the EU)"?
If it's not configurable people will likely complain battery life is higher on the US's software version, they won't care about the reason.
The easiest is to just require it be replaced under warranty - if the battery has to be usable to 1000 cycles, and it is at 80% and 999 cycles but doesn't "work" it's a warranty replacement.
But that then brings in a "how many years" question.
