I mean it is pretty true that most frontend developers do not have the inclination to go trodding into a C++ code base making syscalls without a wrapper. Even taken uncharitably seriously, that is all the comment was insinuating. Everything else is added by you the reader.

And anyway I'm fine with exclusively frontend devs staying out of systems stuff. Anyone that wants to read OS kernel and compiler source code has tons of choices. Most I've talked to find it dry and boring. They don't belong there... that's fine.
