I like that very much. It didn't make sense why they should have match in the first place. I pity those authors who have used such attribute substring selectors hacks to filter or target Gecko.
I should add that doesn't this lead to the situation that allow authors to separate present UA from future UA (possibly those currently in alpha or beta) that change their behavior in handling these selectors.
So to stop authors from using them improperly for Gecko (if that was the intent of the resolution) now results in them possibly being used more often in the future across a wide spectrum of UA.
I have only used them once in one test case and I will never use them again. I never needed to separate Safari, Opera or Gecko anyway, they are all good browsers. :-)
