I have, and I'm pretty sure a quarter of the corporate people I worked with wouldn't be able to point to me the Java logo in a lineup with other logos. Another quarter wouldn't know what a Java is. The rest wouldn't even know there's a thing that runs their programs. How would the logo of a single library in the myriad a company use be even brought to attention?

I'm almost positive that if we dig in a modern project dependency tree deep enough we'll find at least a couple that have an inappropriate joke in the readme or in the documentation. So how would recutils be any different?
