Got your points. Let's postpone this one.

But I want to emphasize that this patch (and the thin PCM) will decrease the performance. While LTO can save the regression, LTO is not widely used. (ThinLTO can only mitigate this.) I mean the default behavior shouldn't cause performance regression. We can offer a new alternative  for the users but we can't enable that by default simply now.
