If I had Flash on my phone, I'd definitely want it to have functionality like you describe, where you have to tap to enable it. I'm sure it won't be that way out-of-the-box, though, and only a small minority of users would know to install a ClickToFlash equivalent even if it were available. So the default and by far most used configuration will be one where Flash is running much of the time that 3G is running too. I certainly agree with you that it's not a dealbreaker for Flash in web pages to not be backgroundable. And I'd prefer it to be the case that it's not backgrounded in the general case.
