I haven't profiled our Windows kernel driver across different kernel versions (maybe I should!) but I'd like to offer this perspective: the kernel is incredibly stable from my driver development point of view. The biggest reason we ship different drivers for Windows 7/8/10 is just that newer WDKs don't support anything older than 10. The kernel has remained remarkably consistent while still offering new features we can take advantage of on non-legacy systems.
