I changed this in 0734f24b. Though most endpoints are under *groups*, tracking down a specific route is very confusing if you don't already know where to look. If you found a bug in *policies* you would have to trace your way from *Otter* to *OtterGroups* to *OtterPolicies*, and it may not be immediately clear that you want the root route. Having all of the primary routes collected onto a single application is explicit and easier to grok.
