Okay. Data-loss what what my brain thought, a sentence about integrity
came out of my fingers.

That would be cool. But I think there would as many, maybe more, cases
of batteries being removed, power cords yanked, and generators turning
off causing shutdowns than low-battery issues.

Also, a point wad made: the more writes you defer, the more memory is
used to store them, on an already memory-constrained system.

Not that I don't think UBIFS would be awesome, with an amount of
tweaking to hit the sweet spot miniamsing memory usage, data-loss, and
keeping write speed up, etc. Just thinking about the downsides.
