This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
* When an error is raised when checking route constraints, we
can only return true/false which either lets the request
through or return a 404 error. Therefore, we just skip
rate limiting here and let the controller handle the
rate limiting.
