I'm not talking about generating a few lines instead of importing left-pad. In recent PRs I've had:
- Implementing a scheduler from scratch (hundreds of lines), when there are many many libraries for this in Go.
- Implementing some complex configuration store that is safe for concurrent access , using generics, reflection, and a whole other host of stuff (additionally hundreds of lines plus more for tests).
While I can't say any of the code is bad, it is effectively like importing a library which your team now owns, but worse in that no one really understands it or supports it.
Lastly, I could find libraries that are well supported, documented, and active for each of these use-cases fairly quickly.
