I've seen this argument made frequently. It's clearly a popular sentiment, but I can't help feel that it's one of those things that sounds nice in theory if you don't think about it too hard. (Also, cards on the table, I personally really like being able to pull in a tried-and-tested implementation of code to solve a common problem that's also used by in some cases literally millions of other projects. I dislike having to re-solve the same problem I have already solved elsewhere.)

Can you cite an example of a moderately-widely-used open source project or library that is pulling in code as a dependency that you feel it should have replicated itself?

What are some examples of "everything libraries" that you view as problematic?

Anything that pulled in chalk. You need a very good reason to emit escape sequences. The whole npm (and rust, python,..) ecosystem assumes that if it’s a tty, then it’s a full blown xterm-256color terminal. And then you need to pipe to cat or less to have sensible output.

So if you’re adding chalk, that generally means you don’t know jack about terminals.

Some people appreciate it when terminal output is easier to read.
If chalk emits sequences that aren't supported by your terminal, then that's a deficiency in chalk, not the programs that wanted to produce colored output. It's easier to fix chalk than to fix 50,000 separate would-be dependents of chalk.

Chalk appears to be a great example.
I wonder how many devs are pulling in a whole library just to add colors. ANSI escape sequences are as old as dirt and very simple.
Just make some consts for each sequence that you intend to use. That's what I do, and it typically only adds a dozen or so lines of code.

In the Python world, people often enough use Rich so that they can put codes like [red] into a string that are translated into the corresponding ANSI. The end user pays several megabytes for this by default, as Rich will also pull in Pygments, which is basically a collection of lexers for various programming languages to enable syntax highlighting. They also pay for a rather large database of emoji names, a Markdown parser, logic for table generation and column formatting etc. all of which might go unused by someone who just doesn't want to remember \e[31m (or re-create the lookup table and substitution code).

  Exactly! ANSI escape codes are old and well defined for all the basic purposes.
  Pulling in a huge library just to set some colors is like hiring a team of electrical contractors to plug in a single toaster.

I appreciate your frustration but this isn't an answer to the question. The question is about implementing the same feature in two different ways, dependency or internal code. Whether a feature should be added is a different question.

The problem isn't the implementation of what I want to do. It's all of the implementations of things I never cared about doing. And the implementation of what I want to do that is soooo much more complex than it needs to be that I could easily have implemented it myself in less time.

The problem is also less about the implementation I want, it's about the 10,000 dependencies of things I don't really want. All of those are attack surface much larger than some simple function.
