Indeed a software used by thousands of commercial products and millions of enterprise applications with ZERO dollar support from either must be maintained at perfect, bug free level by lazy volunteers. Because internet demands it.
Would it even be possible to create today's software ecosystems by mandating all libraries are maintained and supported to the strictest standards?
That would be the end of open source, hobbyists and startup companies because you'd have to pay up just to have a basic C library (or hope some companies would have reasonable licensing and support fees).
Remember one of the first GNU projects was GCC because a compiler was an expensive, optional piece of software on the UNIX systems in those days.
That would be the end of the software industry. No company outside of aerospace and medical devices is capable of delivering this and I even have my doubts about those two, though at least they are trying.
