It seems like my email was not clear enough? What I tried to make clear
is that I think that there is no way to solve the flash wear issue with
the traditional block interface. I think that F2FS in combination with
the zone interface is an effective solution.

What is also relevant in this context is that the "Flash drive lifespan
is a problem" paper was published in 2017. I think that the first
commercial SSDs with a zone interface became available at a later time
(summer of 2020?).
