Some applications really need to be stateless. What if you don't have wear leveling because you're on some bizzare embedded thing?

You could have a one-time written random seed though, which would be enough when combined with an RTC, and would probably still be enough when combined with the almost universally present HWRNGs built into everything now.

RTCs themselves nearly always seem to have about 56 bytes of memory, but I'd hate to see half of that used just for RTC, I'd rather it be exposed to applications via the FS somehow.

But, it could be enough for a 64 bit counter, which would be combined with a one time written secret.
