The quote is to describe the aforementioned integration trope, not sure it has a succinct name beyond that hence the long description in quotes. It first got really popular when it was note one of the iPhone A* processors added JavaScript specific rounding to much "that's how safari can be so great on this device release, it integrates straight to the hardware" only to find out from a safari dev it hadn't even gained that yet. Yes end to end integration is a huge boon to a consistent user experience but it doesn't change efficiency nearly as !uch as some like to think, certainly not more than can be gained from normal optimizations still available and it's certainly not the ultimate goalpost even for consistent experience just a great aid.
Put = out, please forgive mbile keyboard while on a plane :). I do like the level of creativity for an http put benchmark though!
