Why River and Loch frigates could not simply appear before the war

The later frigates embodied combat and mass-production lessons learned through building and operating Flower-class corvettes.

Question

What would make Britain plan large River-, Loch-, and Bay-class frigate programs before the Second World War?

Short answer

An earlier conflict or crisis would have to generate the operational and construction experience historically gained from the Flower class.

Notes

River-class design combined merchant-yard construction standards with wartime escort experience, so ordering the final form before 1939 requires supplying those missing lessons. Flower-class construction taught Britain how civilian yards could mass-produce ocean escorts and what operations demanded from them. An earlier crisis involving Italy or Japan would need to force a Flower-like crash program before Britain could advance to Rivers and Lochs. An earlier hot Abyssinian crisis or conflict with Japan is offered as a way to force that learning before the Second World War.
