As a security guy, for years, you get laughed out of the room suggesting devs limit their dependencies and don't download half of the internet while building. You are an obstruction for making profit. And obviously reading the code does very little since modern (and especially Javascript) code just glues together frameworks and libraries, and there's no way a single human being is going to read a couple million lines…
The "solution" would be using a language with a strong standard library and then having a trusted 3rd party manually audit any approved packages. THEN use artifactory on top of that. That's boring and slow though. Whatever I want my packages and I want them now. Apart of the issue is the whole industry is built upon goodwill and hope. Some 19 year old hacked together a new front end framework last week, better use it…
Standard libraries should include everything needed to interact with modern systems. This means HTTP parsing, HTTP requests, and JSON parsing. Some laguages are excellent (like python), while some are half way there (like go), and some are just broken (Rust).
External libraries are for niche or specialized functionality. External libraries are not for functionality that is used by most modern software. To put your head in the ground and insist otherwise is madness and will lead to ridiculous outcomes like this.
