Yes, it takes some code, but it only needs to be written and debugged once. Then tuck it into you comm library behind a simple interface and forget about the gory details. This is a problem that can be solved completely in user space. Adding a new system call to handle it is adding complexity to the kernel for no good reason.
It is not a better solution just because it takes less code (in user space).
