To play devil's advocate, what's the real-world need to skip to Kaby Lake over Skylake? Personally think the screen, SSD, graphics card, and housing improvements are just as important or more than the CPU differential. Maybe it's a deal if you don't have discrete graphics...
My 2012 Macbook Pro is still quite fast, the only really outdated things are the SSD, graphics card, and battery.
