It's not just obscurity, it's increasingly difficult to trust the governance and quality of code of any outside library. A lot of deps in code are unnecessary you use maybe 1-10% of the api surface. But since building and maintaining software can be cheaper now it can be better to maintain a 1-5k LOC vibe coded version that meets your security bar than to trust an external party's governance & quality. This has the additional benefit of reconsidering if you even need the dep or if you can reuse something you already have (since you may not want to maintain the lib).
