How important is the optimistic matching feature?

The optimistic matching case is the only case when the return path is NOT the same as the input path.

```
const {path, value} = switchPath('/home/foo', {
  '/bar': 123,
  '/home': 456,
});
// path is `/home`
// value is 456
```

This means we have to use the returned path not th imput path. 

Would this feature be missed?
