It seems reasonable to also apply the P1787 change to C++20, treating it as a missing piece of the DR2237 resolution. It seems undesirable to apply it to C++17 as well. But it would be helpful for -Wc++20-compat to flag this compatibility issue Incidentally, we should probably also reduce the C++20 error to a pedwarn.
