We're not talking about write endurance though? From what I've read, unpowered SSDs only hold the data for a year or two, regardless of the age of the drive.

You've probably been reading bad sources. There is a very real relationship between the number of P/E cycles that a piece of flash memory has been through and the unpowered data retention it can provide. Lots of publications and even more random forum posts repeat statements about SSD data retention without including the caveat that the numbers apply specifically to worn-out drives. Brand new flash memory can easily have unpowered data retention in excess of a decade.
If you're reading a source that claims SSD unpowered data retention is only a year, and that source does not qualify that with a statement about the prior condition of the drive, you should assume that you're reading another misinterpretation of the JEDEC standards.
