>This seems like an argument that says that Apache Arrow is as important as the paper clip, which would be an extraordinary claim.

I picked the first office supply object that came to mind. There are better examples.

For example, why have the bulldog clip as it's own article when you already have binder clip?

https://en.wikipedia.org/wiki/Binder_clip

I highly suspect that with some actual effort I could find an even less deserving office item.

And you may be right that Arrow needs to do more to be notable and ready for its own page. But ignoring some objective standard and instead looking at a relative standards of other articles, it does feel like there are some unequal requirements in this regard.

The binder clip article has many of the same merits as the paper clip article. The bulldog clip article is more interesting: it's a "stub" article (its authors are explicit about the fact that it's not a complete article), and still it manages to track down some of its history and cite interesting uses from books – someone had to read those books and fish the bulldog clip cites out of them.

I think it's pretty clear to anyone why bulldog clips are in the encyclopedia, and it is only clear to subject matter experts with strong opinions why Arrow would be.

If your topic requires subject matter expertise in order to recognize its importance, the standards are unequal: you are going to need to do more work to establish its notability, because you cannot reasonably expect the layperson volunteers in the Wikipedia project to do that work for you.

An item which almost every office worker has seen or used is definitely notable enough to get an article. Yet another data format among hundreds which has yet to reach a wider audience could be, but it is not obvious.
