Request Map :params isn't necessarily Map of keyword -> String

[terjesb]

http://pedestal.io/reference/request-map says that :params is a Map of keyword -> String.
Is this true if one doesn't add keyword-params to the default interceptors?
:params by default seem to use strings for form-params, even if they are keywords in :form-params.

In short, :params by default seems to be a map of keyword or String -> String.

lein new pedestal-service ps
;; verify project.clj is using pedestal.service 0.5.2
in service.clj add handler:
(defn post-test [request] (ring-resp/response request))
and route:
["/test" :post (conj common-interceptors `post-test)]

curl -X POST -d yo=lo localhost:8080/test?any=thing returns:
:params {:any "thing", "yo" "lo"}
:form-params {:yo "lo"}
:query-params {:any "thing"}
