This isn't exactly what you asked for, but how about a custom command, such as Set, that calls a function to do the option set in a try/catch? If it succeeds, great. If it fails, you can just ignore it or use an echomsg or something.
You won't know when a feature was introduced, but you also won't have to have existence checks around everything.
