> Do you not run tests? Know how to grep? If individual deprecation warnings have to be specifically enabled, people who don’t read release notes describing them won’t search their source code for possible future problems, and their tests won’t signal any issues before a feature is removed, or (possibly, for other deprecations) behavior is silently changed. Deprecation would be worth zero for such users.
