Describe the Bug

Optional catch all route at pages/[[...slug]] works fine on latest version until I enable concurrentFeatures in next.config

Expected Behavior

I should be able to catch the index and all routes using concurrentFeatures option.

To Reproduce

repo to reproduce it: https://github.com/vndre/catch-all-next12

1) browse to localhost:3000/... catch all route should work for any route. 2) uncomment line 4 to 6 in next.config.js 3) next throws error: You cannot define a route with the same specificity as a optional catch-all route ("/" and "/[[...slug]]").

This seems to have been fixed on canary already! Please upgrade if you want to try it now.
