I don't think "they" have changed their philosophy -- if you don't
know what to do, you should at least log that you encountered that
weird case.

Those of you who use the PathScale compiler may remember the
occasional "Not yet implemented" error message -- it's a great way of
getting QA or a customer to provide example inputy to use to develop
working fixes for weird cases.

Filesystems are easy: you just inject errors, and you'll hit most of
the corner cases. Right now that means silently wrong answers or
crashes, with no clue as to where the problem is.
