But if that was the case, you would do that, resorting to other tools for something that tiny is silly and only really done by beginners. Something that tiny would also unlikely have bug or documentation issues.

There are some great tools that are poorly documented/buggy, yes, but they are quite rare and it's much easier to use them and fork the repo (if inactive) than to build from scratch.

This idea that you avoid creating a dependency mess by writing more of your own work, isn't the entire truth. The dependency is just internal, and far more likely to have poor documentation than open source plugin #4159. So you really haven't solved or avoided the problem at all.
