There are billions of Linux systems in the world. They have a default. If you change the default for your own distribution, you're the oddball, and the fact that there are two different values for the default can itself be an issue. It's not possible to change the default everywhere and have everyone adopt your new default. The kernel developers are very careful not to make breaking changes. Just the same, you can write your non-root server and arrange to be launched by a service manager that turns on the appropriate capability to allow it to bind low-numbered ports, but nothing else.

Yes change it for the next 15 year. Anyway already there's a mitigation by CAP.

> There are billions of Linux systems in the world. There are not billions of Linux servers, desktops and phones, probably high single digit millions or low double digit millions, but I suppose if you include microcontrollers, perhaps. One should be able to configure Linux to reconfigure itself any which way one wants it on reboot without making fundamental changes to all Linux systems everywhere. OP really can't figure a way to run a custom configuration script on reboot? RLY?? I would consider this academic on BSD. Is this something that systemd broke, that one can't pump the special settings back in, and they are just lost on every reboot? Then never reboot. Problem solved. Otherwise, init ftw.

  There are over 3 billion active Android devices https://www.theverge.com/2021/5/18/22440813/android-devices-active-number-smartphones-google-2021 https://www.theverge.com/2021/5/18/22440813/android-devices-...

    That is a very big number, but I wonder how many of those are multiuser, such that there may be concern an unprivileged user might leverage privileged ports to intentionally cause havoc. I know... all of them. Users aren't necessarily people, and usually not.

      All Android devices are multiuser: Android will assign a different unprivileged user ID to each app, because it can't be assumed that apps should trust each other. You definitely don't want random apps to be able to take control of privileged ports.
