Could the XZ backdoor have been detected with better Git and Debian packaging practices?

Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
Author has some good thoughts, but it's important to mention that the xz backdoor did not make it into debian stable, only sid.
Debian already had policies to handle stuff like this, which is how bookworm wasn't affected.
There was a bunch of luck involved that Andres Freund detected this. Give more time, it would have ended up in stable releases eventually if not detected.
