Fw: JEP 455: Non-enhanced switch statements

[Attila Kelemen]

If such a warning would be implemented, would it be possible to also add
selective `-Werror` (same syntax as `-Xlint`)? Because then it would be
possible for people to turn on "exhaustive switch" at will (which would be
awesome in my opinion). Selectiveness of `-Werror` is necessary for this,
because there are warnings that I wouldn't want to turn off, but don't want
an outright build failure, because of them. Also, selective `-Werror` would
be useful for some other warnings as well.
