With this patch, I'm flipping the polarity of things. The flag `-enable-experimental-feature ManualOwnership` now turns on the diagnostics, but they're all silenced by default. So, you need to add -Wwarning or -Werror to your build settings to turn on the specific diagnostics you care about. These are the diagnostic groups relevant to the feature: - SemanticCopies aka "explicit copies mode" - DynamicExclusivity For example, the build setting `-Werror SemanticCopies` now gives you errors about explicit copies, just as before, but now you can make them just warnings with -Wwarning. To opt-out a declaration from everything when using the feature, use @_noManualOwnership. @_manualOwnership is no longer an attribute as a result. resolves rdar://163372569
