iOS8 legacy support is dearly needed. There are hundreds of millions of iOS devices out there that can't upgrade to iOS8. It is a pity that Apple doesn't offer iOS8 support for these machines. Apple would make a lot more money off of them if these users could stay current. It would be more secure and simpler to offer tech support. It would keep users 'in the fold'. It is very doable with graceful fall backs at the compiler make level for any features the older hardware can't support and that wouldn't affect new iOS devices at all. Makes are already target specific.
