Ok, let us agree on this one then ;)

There is still kind of a dichotomy regarding the entire issue. While
in many cases, noone will complain about a few  seconds of lost data,
it is an entirely different beast if you lose an entire file that may
have been added to and maintained over month/years, just because the
system went down at an unfortunate moment. In my opinion, having a
consistent, yet possibly somewhat outdated file, is much more
important than having the most recent view in an inconsistent/broken
state.
