But the answer is in those articles already.
MRAM data retention isn't indefinite. Having absolutely no mechanism to deal with that and just accepting that data that has been in the caches for a while could be corrupted seems unlikely and no one is going to sacrifice density and performance on an L1 MRAM cache to get 10 years of data retention.
If the data becomes unreadable within a day or so the problem solves itself. Anyone who can steal and take apart the chip and read out millions or billions of bits within hours simply has too much ressources available to guard against effectively.
