Nah, it's simply a bug that files which are being stored in order to
recover your work after something went wrong --- and that "something"
includes having to reboot --- are being stored in such a way that
recovery is impossible.  It's a feature that doesn't work right and
thus needs to be fixed.

If people want to configure things so that they are broken, that's up
to them.  Intentionally choosing defaults for software in such a way
that the software isn't safe to use is not sane.

It would be like making guns with safety levers (or how ever they are
called) that shoot you when you use the safety lever for the safeness
it is supposed to provide.  Maybe that works when the majority of
people is insane.  Are we there yet?
