You're holding a grudge over a product that came out 9 years ago, never mind that it got 5 years of updates. The vast majority of new iOS features are supported on older products. The few features that aren't supported by old devices are probably disabled for good reasons that came up while engineering. For instance, I publish a kext that patches the macOS kernel to enable you to use certain Thunderbolt devices that are blacklisted. They are probably blacklisted because they do not follow the Thunderbolt spec properly, and could destabilize your system. Just because I can hack it to work, doesn't mean it's a good idea.
