Not exactly, distribution conversation aside this is specific to kernel extensions. Apple's been moving drivers out of kernel space and into user space for several years [1]. There's a lot of good reasons for doing so, and not a lot of drawbacks. I'd consider this to be a strongly worded API deprecation notice.
