This case not withstanding, Apple regularly includes patches to the built in CLI tools in security updates, so it's a little disingenuous to suggest those tools are not really supported.
I read GP as a descriptive comment not a justification. They are showing with this issue that they don’t truly support the cli tools in a way we ought to rely on. Whether they occasionally provide some support doesn’t mean they’re supported. Only full and competent support counts, everything else counts as “it’s best-effort at best”
