Could we use fs-routes with paths outside of app directory?

[dpeek]

I doens't seem like it's possible to use fs-router with paths outside of the users app dir right now.

I'd like to build a framework that provides a bunch of standard routes out of the box (for auth, profile management, etc).

Right now I'm declaring the routes "manually", but it would be nice if I could just use the same conventions of the file based router for the framework routes as well.
