I would like to know the details, seriously. Thousands of broken packages because of major python release?

As a former package maintainer I can assure you that every update of gcc breaks the build of some other package. And we are talking about C or c++, languages existing longer than Python and having much stronger backward compatibility story. And no one ever said that upgrade to recent gcc is a problem.

Iow there is hardly any up to date system which do not require constant maintenance.
