We actually don’t define `__cpp_pack_indexing` yet, and the other C++26
features that we support that have a feature-test macro are also exposed in
previous language modes, so this would be the first one that’s (currently)
C++26 only (though, again, maybe we want to expose this one in older language
modes too?).
I don’t actually know if this is the case, but I’m assuming the reason why we
don’t define `__cpp_pack_indexing` is because there is a chance that the syntax
might change or something like that?
