We need to mark messages as final soon, but before we do that we need to
provide a temporary opt-out mechanism to accommodate existing code that
inherits from generated messages. For 3.7.1 let's stop marking messages
final but in 3.8 we can reintroduce "final" with an opt-out option.

The removed variable here is actually used breaking downstream bazel
builds.
