What impresses me is that the Linux kernel has maintained ABI compatibility with userspace forever. Meanwhile, people in userspace keep talking about binary compatibility as some kind of impossible unicorn of a goal and bring us terrible things to allow them to "evolve" ABIs instead of just, well, not breaking callers. I love it when Very Serious People say "X is impossible". You then show them an example of "X", and these Very Serious People hem, and haw, or rage-quit meetings, or do whatever it takes to avoid admitting that they were wrong.
