So it's an example of a burden created by package archive growth. https://lists.debian.org/debian-68k/2025/06/msg00048.html It's also related because such an enhancement may involve an ABI break. That's why I mentioned threading a week ago. https://lists.debian.org/debian-68k/2025/06/msg00018.html > Finn accuses me that I deliberately slow down Linux on m68k when all I > do is continue to maintain vanilla Debian on m68k. Citation needed. What I have said is, Debian is bloated (in part) because of its dependency graph e.g. the cmake dep on Qt, which you defended. https://lists.debian.org/debian-68k/2025/05/msg00038.html
