I don't think that's true.  Development in GNU/Linux is highly 
de-centralized, and some projects are better at stability than others.  
Linux has maintained an extremely stable interface for user-space 
applications.  glibc uses versioned symbols for backward compatibility.  
The original question was about forward-compatibility, which is a much 
harder problem.

Not all developers do as good a job with backward compatibility, but 
that problem is considerably more pronounced in the high level 
languages, where versioned libraries just aren't a thing.  And that's 
why you see docker and other containers gaining traction, so that 
applications can be run in an environment with specific library versions.
