Currently, you need to override `stdenv.hostPlatform` to request a compressed kernel on AArch64, and the kernel configuration is split between the central structured configuration and string snippets in platform definitions. This has consequently made the latter bitrot terribly. Since the platform‐specific logic is now very limited after cleaning up the detritus, we can move it into the kernel derivation and expose the relevant configuration there for anyone who wants to customize it further or needs to read it out.
