Agreed, I was not blaming maintainers -- just trying to point out that
the problem is there :-)

In those cases, it is still very useful: we add the `fallthrough` and
a comment saying `FIXME: fallthrough intended? Figure this out...`.
Thus a previous unknown unknown is now a known unknown. And no new
unknown unknowns will be introduced since we enabled the warning
globally.

That's right, I was referring to the cases where the compiler saves
someone time from a typo they just made.

Cheers,
Miguel
