I don't think I agree with that. To me, how low-level something is makes more sense sense as a spectrum rather than a binary, and there are certainly other things that I'd consider to fit into the lower end than just OS kernels. Over the summer I contracted for a company making satellites working on software they had that facilitated interactions between various software and hardware components that had to run a 20 ms loop for processing everything, with delays cascading throughout those other components and causing systemic issues. This was all in userland (the OS stuff was managed by another team), but a tracing garbage collector would have been pretty much a non-starter due to the potential to miss the expected timing of a loop iteration.
You could handwave this objection by saying it's not "really" low level or that "nothing" was an exaggeration, but at that point it seems like we'd be back to the original question of why it's wrong to say that this isn't a primary use case for C++.
