there are lots of programs that access `*environ` directly, so while this might be good, it wouldn’t solve all classes of the problem. There are also uses out there which are performance sensitive (and often just as if not more unsafe, such as holding pointers into the structure over long periods).

threaded programs should probably seriously consider retiring libc, but we don’t currently have a common ground replacement.

name related activities are one of the worst areas, contributing significantly to the glibc linkage and abi challenges, but also lacking sufficient standards for alternatives or even consensus to be built quickly.
