In reply to Niko.

As I’ve said, I’m not really here to discuss UI choices – not because I think they’re not up for discussion or are always right (not at all!) – but because I object to it being done under the framing of a competitor attack that has caused repeated headlines about “WP Optimize Cheating” to be fed into every WordPress install in the world (and because frankly, it’s not my role!).
But for what it’s worth, our main JavaScript developer thinks it’s perverse for someone to claim that you wouldn’t expect the button marked “all” to be doing all that the radio for merely ‘some’ was doing. Excluding “all” scripts does the same for “all” scripts as excluding individual scripts does for those scripts.
And that makes perfect sense to me – after all, as far as I know, absolutely nobody else was confused by that up until the competitor was. Our developer uses the analogy: if the car manual says that you shouldn’t drive the car at 100mph on public roads, then a driver doesn’t get to claim that he wasn’t told he couldn’t drive it at 150mph. The greater obviously includes the lesser.
