I'm not entirely sure that's their philosophy and I don't think they're going to implement RTwP no matter what the costs and benefits are. They could have announced their chosen combat mode months ago and gauged feedback. Now their response is oh but we're too far along now to make any significant changes! That's not how a company genuinely interested in market analysis behaves. I suspect there are principles involved, maybe even pride and haughtiness.
I suspect there was never a question as to which way they would go (TB or RTwP). Some might then say, "well you should have told us," to which they might then reply "we just did." As for if they ever will implement it, perhaps not; but I doubt it would be out of disdain or indifference.
