Package: src:dpkg Version: 1.22.13 the changelog reads:
- Bump minimum required C++ standard to C++14. - Warn on C++17, C++20, C++23 and C++26 extensions usage.While it maybe too late about a minimum C++17, please don't warn about C++17. This is the default since GCC 11 [1], and was already the default for the last Debian release.
Even better, please consider making C++17 the default for trixie. Thanks, Matthias [1] https://gcc.gnu.org/gcc-11/changes.html
