Except with BSDs you are on your own if you go down that route, because there are no stability guarantees.
It is more of an implementation detail for the rest of the C APIs than anything else.

Indeed. Another reason to use the system's macros rather than hardcoding integer literals--the numbers can change between releases. Though that doesn't guarantee the syscall works the same way between releases wrt parameters and return value semantics, if it still exists at all. And I believe OpenBSD removed the syscall wrapper altogether after implementing the pinsyscalls feature.
