would it be better to use the -v flag by default for ninja when possible in Meson/CMake or plain ninja builders for nixpkgs? This would make it nicer to see the full compiler invocations for each object that is being compiled in the build logs.
Debian’s debhelper does this for example (lib/Debian/Debhelper/Buildsystem/ninja.pm · debian/13.14.1 · Debian / debhelper · GitLab) and I generally always thought it kind of helpful.
It might make the builds logs slightly larger but that’s probably not a big issue?
