In general, the reason you use a compiled / typed language like golang at all (instead of, say, perl) is to "left shift" your bugs: A bug caught when you first spin up your application is better than a bug caught after a corner case acts up in the wild, and a bug caught when you compile is better than a bug caught when you first spin up your application.
I recently ran a cross a bug in a side project of mine (using gorilla/mux) where I had accidentally made overlapping routes. If the router had panic'ed instead of running, I would have been nudged to refactor the URLs and completely avoided the bug.
