That's a good point. I do see developers overestimating the difficulty when supporting the use a 3rd part lib. I recently came across a library in our code base that's about 200 LOC including comments, line feeds, etc. The library is in C#, a language that takes a fair bit of vertical space due to braces. So, the actual LOCs are just over a 100. I asked the team why can't we write something this simple ourselves. The reality was they didn't know how to, and it isn't a habit to have even a cursory glance at the source of the dependency they were bringing in.
