Why the Blackburn Roc was not a true stopgap

Why reject the idea that the Blackburn Roc was a sensible stopgap until better Fleet Air Arm fighters arrived?

The Navy was already ordering better fighters and understood that dive bombers, not level bombers, were the central fleet threat; the Roc looks more like a political concession to Air Ministry turret-fighter doctrine.

The Fleet Air Arm had other fighter projects in hand and more experience than the RAF with fleet interception exercises. Because the Navy expected dive-bomber attacks, a slow turret fighter optimized around level-bomber interception offered little operational value. The order looks like a political accommodation, with night combat air patrol among the few plausible attempts to find the aircraft a useful niche.
