I generally find it worthwhile to separate the action-motivating aspects of a framework from the universal-acceptance aspects.
That is, if I endorse the privilege framework because I believe it effectively motivates right action according to my values better than the alternatives, then one option is to embrace it and act accordingly. If my belief is correct, one consequence of that will be that I am more reliably motivated to act rightly by my values. If I also talk about my actions and my motivations for those actions, I will provide evidence of that to others, thereby encouraging them to also embrace the privilege framework (at least, insofar as they share my values, and possibly even if they don't).
In the meantime, they won't, and (as you say) we won't be perfectly efficient. Hysteresis is like that.
The advantage of hysteresis is that if it turns out I'm wrong and the privilege framework doesn't optimally motivate right action, there's a greater chance of collecting evidence of that truth before we've collectively invested too much in a suboptimal practice.
Given how often we're wrong about stuff, that seems like a worthwhile advantage to preserve.
I could probably word that more succinctly as "Practice beats proselytizing."

Whatever happened to the corresponding-to-reality aspect?
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
