Research direction
Start by locating the TypeScript declarations for Component.Instance and Component.Options and inspect how their fourth generic parameter, TBehavior, is defined in the 4.0 typings. Check existing usages without a behavior type and verify that the declarations type-check with that parameter omitted while behavior-enabled components still retain their typing.
