$ grep -roh 'syscall(SYS_[a-z]*' src/kits/kernel/ | sort -u
syscall(SYS_exit
syscall(SYS_futex
syscall(SYS_gettid
syscall(SYS_tgkill
And this is just from a fairly small library of mine.

Really depends on how you define "applications".
Basically why I asked the question - if the above should also be
wrapped, I am all for it. But if not, why some syscalls are special?
