What's your point? Are you going to create the magical patches that make that happen? Are you going to maintain the added complexity that comes from suddenly having multiple dirty bits per "page"? Are you going to create the mythical filesystems that magically start doing tail packing in order to not waste tons of disk-space with small files, even if they have a 32kB block-size? In other words, your whole argument is built in "wouldn't it be nice". And I'm just the grumpy old guy who tells you that there's this small thing called REALITY that comes and bites you in the *ss. And I'm sorry, but the very nature of "reality" is that it doesn't care one whit whether you believe me or not. The fact is, >4kB sectors just aren't realistic right now, and I don't think you have any _clue_ about the pain of trying to make them so. You're just throwing pennies down a wishing well.
