Comment:

 Plus xnu-headers is installing old xnu headers on older systems rather
 than newer userland headers (which are still compatible with older
 systems).

 ​mfeiri should update xnu-headers to always just install the latest
 headers.  There may be a need to fetch additional headers from an older
 release for removed architectures, but other than that, you should just
 always be using the latest headers.
