I think it's mainly a fix/workaround for the breathtakingly antiquated build systems in the C/C++ world ;)

In the end, STB-style single-header vs. a single .h/.c pair is not all that different, both are equally straightforward to integrate into a project.

The actual problem are libraries made of dozens/hundreds/thousands of header and source files and coming with their own complex build system setup.
