For me personally, I would live Web Bluetooth to be supported (However its classed as a experimental technology), however until its supported in Safari iOS I'm not going to loose any sleep over it being missing.
Import-Maps is another very important one.
I get that business becomes gamified to try and squeeze the most profit as possible. It happens because the big wigs only look at the numbers, and it's not anyone in particulars fault. I can imagine a new manager of sorts trying to make a name for themselves in a big company such as Google, suggesting that stopping ad blockers could make X Million $ more per year and they might even get a promotion for it.
Safari supports and will continue to support v2, but Safari never supported blocking webRequest.
