You must have missed some of the related posts over the past couple of years in the dev sub-forum.
People have been reporting eMMC failures on devices as new as the PW2 from time to time.
Now those would be the ones that fall into the part of the MTBF curve for earliest likely failure (and the rest out there are still years away).
Also some are most likely battery failure related rather than erase - reprogram wear.

But I don't think hard and fast rules can be set.
A battery that falls at the longest lifetime end of the MTBF bell curve will out last the eMMC.
An eMMC that falls at the longest lifetime end of the MTBF bell curve will out last the battery.
And there is a lot of overlap in the curves of both parts.

Plus, both part design and device design has not been fixed and stable over the time period now available.

Nope, just too many variables now to set hard and fast rules.
