I've worked lots of smart engineers who use these sort of "just-for-fun" tools, or simple hacks. At the time I often think exactly as you do, "why do I need a whole dependency..." And often I leave feeling the same way. But more than once-as simple as putting null before equalities in conditionals, or as complex as setting up squid to cache just robots.txt for a crawler-I've been surprised and glad that I'm working with that quirky dude who insists on paying a small price for something useful. And I find myself using it again in the future because it actually gave me real value, made me and my team more productive, or happier, and hopefully made our product better.
