Updated version of v3: https://gcc.gnu.org/pipermail/libstdc++/2025-July/062772.html
Notably it (finally) removes the debug assertion. It should be applied after (at least that's the order I test them in locally): https://gcc.gnu.org/pipermail/libstdc++/2025-July/062727.html It might be safer to also apply the "Improvements" patch series first, since updating std::dims and std::aligned_accessor is much easier than the reverse.
