Would the Royal Navy have coined the term 'heavy cruiser' without naval treaties?
Short answerProbably not, because treaty rules created the need for that distinct classification.
NotesWithout treaty definitions, Britain would have little need for the term heavy cruiser. It could describe ships by scouting, escort, or presence duties. Dividing them into heavy and light categories narrowed that flexibility. The argument favours descriptions based on the job the cruiser is intended to perform.
