One of the motivations for performance.now() was to get requestAnimationFrame to use it, per this discussion: http://lists.w3.org/Archives/Public/public-web-perf/2011Aug/0039.html. Seeing that developers were aware that they were using prefixed code that could still change behavior and requestAnimationFrame spec has only now just gone into Last Call, I don't think it's too late to make such changes.
