Well, it depends on what your goals are. If you're an advertiser, yeah, poor Flash performance is a big deal. You don't want your Flash ads to be an opt-in only deal because people are tired of their shit being slowed to a crawl whenever you try selling them Gatorade. So I could see why people would push for a different standard there. But as an end user? Hell yeah, I want opt in Flash compatibility. These things aren't amazing multi-taskers to begin with, and as meme Hitler pointed out, sometimes a man just wants to play Bloons, in which case the performance hit really doesn't matter.
