I'm quite sure some edge cases could be forbidden to speed ip parsing. The most common use in my experience is simple nesting ("& .child"), and I would argue other forms should be avoided for readability reasons anyway. But finding 3 other solutions (because of "performance"), not promoting them through transpiling, and then forcing them on web devs seems... googley. Not the first improvement they forced down our throats and unfortunately not the last. /rant
