What do you propose, then?  Build a custom UAPI header package with
the most recent upstream system call list, but otherwise with the
contents for the kernel version for the distribution release branch?

The downside is that you get SYS_ macros for system calls which are
not implemented in the distribution kernel.  (Quite a few, arguably
broken, applications use #ifdefs instead of run-time checking.)
