This conveniently sidesteps the whole issue of getting DWARF data in the first place, which is also still a broken disjointed mess on Linux. Hell, Windows solved this many many years ago.
You'd need a pretty special distro to have enabled -fno-asynchronous-unwind-tables by default in its toolchain.
By default on most Linux distros the frame tables are built into all the binaries, and end up in the GNU_EH_FRAME segment, which is always available in any running process. Doesn't sound a broken and disjointed mess to me. Sounds more like a smoothly running solved problem.
