// thread), but should be safe to use on threads other than the main thread (so
// that worker threads can have extension bindings).
// TODO(devlin): Rename this to be simply "ExtensionBindingsSystem"? There's
// no non-native version, but the rename causes churn and also makes git history
// a bit messy (since there used to be a different ExtensionBindingsSystem).
