You know a lot about binary compatibility ;-)
Yes we care too. The beauty of Debian package management and release
management is all about maintaining binary compatibility.
Relax and learn how we do it through our documentation listed at:
https://www.debian.org/doc/
https://www.debian.org/doc/debian-policy/
https://www.debian.org/doc/manuals/developers-reference/index.en.html
