Exactly. I think you're doing fine. It's weird that you're using C++ here, since that brings in a lot of crap, but then your programs are probably C++ anyway, so it's not a problem.

Honestly I'm impressed by this work. It's a thankless thing to have built, it's definitely feasible to build but more work than almost anyone would have been willing to do. What would be even neater is if Musl had this builtin.
