I'm not a C programmer, so it would probably personally take me days, maybe weeks to fully grok 5K SLOC of C. Still, it is potentially possible if I made the effort, unlike with other programs, like you say.
It's a testament to the quality of the original C code that I was able to configure and use st and other suckless tools with my limited experience. An experienced C developer would probably find it a breeze.
