That's not my point. My point is that if executable A depends on library B, and library B does not provide any stable ABI, then the package manager will take care of updating A whenever updating B. Windows has fanatical commitment to ABI stability, so the situation above does not even occur. As a user, all the hard work dealing with ABI breakages on Linux are done by the people managing the software repos, not by the user or by the developer. I'm personally very appreciative of this fact.

Sure, it's better than nothing, but it's certainly not ideal. How much time and energy is being wasted by libraries like that? Wouldn't it be better if library B had a stable ABI or was versioned? Is there any reason it needs to work like this?
