Note: I'm intentionally not using CompositeDefaultsObservation for simplicity, as it's not really needed here.

Curious about this. I thought that invalidate() would be thread-safe with Lock,
Should we use DispatchQueue.sync instead inside the DefaultsObservation?

I'm not 100% sure. I have seen KVO crashes in some of my apps that may have been caused by some threading problems in macOS. I prefer to keep it limited to this code until I can 100% confirm it. This is just a precaution.
