protected IObservable<T> GetOrCreateObservable<T>(T defaultValue, string? key = null)
Summary:
Returns the live observable stream for a settings property, creating it on first
access. The returned observable emits the current value on subscribe (starting
with defaultValue until the cold load completes, then the
persisted value) and re-emits whenever SetObservable
is called for the same key.
