Actually providing a method rather than documenting the syscall would be a good start. libc patches over a lot of syscall requirements and side effects, as well as keeping track of the individual syscall numbers for you.

I'm kind of surprised glibc doesn't provide a normal interface yet, but I suppose it has to do with non-Linux compatibility?

glibc has been reticent about adding new syscall wrappers for a few years. The situation did improve for a bit recently (and they added something like 5 years of syscalls from their backlog in the past few years) but I'm not surprised it's taking some time.

Thankfully we have had unified syscall numbers on Linux (for almost all architectures) for the past few years so tracking them is less painful than it used it be.
