I see some messages with paramvalidator in their keys in languages/i18n/en.json, and I also see some in includes/libs/ParamValidator/i18n/en.json.
Is there a good reason to have them in those two places, or can they perhaps all be in includes/libs/ParamValidator/i18n/en.json?
My hunch is that they all belong in one place, but correct me if I'm wrong.
Or maybe they should move from languages/i18n/en.json to includes/api/i18n/en.json. People who know ParamValidator well should decide.
