I'm trying to get a hold of the Kernel Headers for 10.14 Mojave, but even though the Beta version (even two actually) was already released, XNU's repository (both here and here) is still only up-to-date with High Sierra.
I also tried getting Command Line Developer Tools but they only contain User Headers (and maybe a few but not a lot of Kernel Headers).
Anything else I could do? I don't really need the Kernel source as a whole, only its headers.
For Dark Mode to work, I needed Xcode 10 beta. Thanks to user128998 for helping me out!
The current latest version of the three iWork apps (as mentioned in the question), are supported on macOS High Sierra 10.13 and iOS 11. You are right, that the apps as well as the OS will be well supported into the future.
However, as mentioned in the release notes for the apps, certain features require the app to be running on macOS Mojave and Siri shortcuts requires iOS 12 which is the first iOS version to support this feature.

Apparently XCode command line tools doesn't install the headers by default anymore. However, it does provide a package in
/Library/Developer/CommandLineTools/Packages. On my system it was/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg. I installed this package and then the headers showed up in/System/Library/Frameworks/Kernel.framework/Headers.
