I understand it's likely a request that won't be granted, but that's the topic of this discussion, so it is what it is.
I'm never saying the fix to the bugs is to downgrade... I'm suggesting that reverting back to iOS 6 so you don't have to endure the bugs while Apple fixes them is best.
Nobody knows how long it will be before every bug is fixed, but things generally ran quite well on iOS 6. I feel even worse for those that use their devices for business and interacting with clients... bugs for them must be awfully difficult to endure, and at times, embarrassing. When you're trying to display something to a customer and Safari crashes, springboard restarts, etc... Battery dies though it was at 12% still.
Please don't think I feel Apple should offer iOS 6 indefinitely. But since those people enduring bugs are not contributing one bit to the solution, letting them run iOS 6 until the bugs are ironed out is just the right thing to do.
It'll be a while until everyone moves up anyways. My iPad 1 and 3GS run iOS 5/6 just fine with no app issues yet. I don't expect this to be the case forever, as developers are no longer designing for these pieces of hardware or software, but even still it's pretty good until I upgrade my hardware. For now, they run better than my iOS 7 iPhone.
And nobody's "pouring" any more effort into iOS 6. I don't know why you think that, as everything currently works fine on iOS 6, and extending the window for a few weeks/months/whenever they fix up iOS 7, really doesn't take any additional effort. You make it sound like they'll have to take everyone off the iOS 7 developments to support iOS 6, but it's set up for a little while.
