Should be ok to fix, due to:

• Looks to be defined on InternalRouteInfo which implies private? This method does not appear to be used in emberjs
• Also quick github search suggests, this is only appears when folks have vendored route.js
• https://emberobserver.com/code-search?codeQuery=shouldSupercede turning up nothing
