Limited write cycles will produce data corruption, but what the article explains is that Apple is using the Flash in M1 macs in a similar way to other ARM devices, that is, they have the firmware there.

I don’t know how much time do you expect your mac to last, but write cycles on your firmware should not be much of a concern.

Right, but I get the impression that the firmware vies for space with the rest of / et al.

Sooo that means the wear leveling had better be ahead of whatever lifetime writes you throw at the system, or...

Easy to account for in drive firmware. Not to mention the file system if that were actually being used. Way back when, master boot records were duplicated at know locations for kinda similar reasons.
