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
