PN ... agreed on UK tone-down, although RAFG would have a different argument as the threat from tactical aircraft was more significant.
Your point on PRSL [new term to me, but I know what you mean] is well taken. That's where I would envisage, for example, deploying radar reflectors and other signal generators in an attempt to create false offsets/IPs. It won't fool everyone, but anything that diminishes the weight of an attack is of value: high-speed approaches to targets in a hostile environment leave little room for error, and if those can be created there are tangible benefits.
