--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
For C++20 this was fixed by:

r16-3733-g88d4738ddc9ca3
    libstdc++: Document C++20 atomic_ref implementation-defined behavior.

r16-3734-g2ec29759bab844
    libstdc++: Document remaining C++20 implementation-defined behavior.

and this was related too:

r16-4195-gdeb7e9312adc02
    libstdc++: Add C++2020 Implementation status table.

So I've removed c++23-lib from the blocker field
