That happens a lot, or more frequently it's some library already being used that is overcomplicated and won't work with something else I need it to work, like a build tool, or is in a cross platform language like node but doesn't work on one particular, major OS. But when this happens it's maybe never the case that it would have been reasonable to write it myself. I just have to find a less shitty alternative library. In general, it's blatantly obvious when you need to do which, you have more much bigger other problems, the chance of this issue even popping up is pretty low, and the resolution is probably fairly straightforward.
