(In reply to Rene Ladan from comment #16)
Well, this submittal was not done case by case but for C++20
overall. That leads to issues like std::source_location, which
https://libcxx.llvm.org//Status/Cxx20.html lists as covered by
llvm16's libc++ :
P1208R6 LWG Adopt source_location for C++20 Cologne Complete 16.0
That "16.0" is the "First released version" column's content.
(I've not reviewed the full list. I just happened to remember
the "not there yet" status of this one from looking into its
status a while back. If I remember right, there are other
areas still classified as "experimental" in llvm15's libc++
but I've have to look up any details.)
