But in some cases syscalls are more convenient than reading/writing/ioctling
in /proc, /sys or /dev.

Now as I understand creating new syscalls for "home" use is not encourahed.
It is not guaranteed that tomorrow new syscall will not be introduced
in mainstream kernel. So portability issues is not considered for
"home" modules.

And I suggest to regulate syscalls usage and reserve a set of numbers
"home" modules used in some organizations only.

I don't think that they all will use only devices and /proc and /sys
to communicate
with their modules.
