Whenever this comes up I feel it is worth pointing out that Linux's "Things break" approach is a problem exclusive to the userland tooling built up around the kernel. Linus takes a very hardline stance against breaking kernel ABI compatibility (except for drivers), but pretty much every piece of software outside of that, including GLIBC, thinks it's totally ok to break things all the time.

It's really very sad that the Linux community never adopted Linus's view.
