Author couldn’t help himself but do some “wisdomry” at the end!

That’s a question of API, not type system. And FD types (e.g. OwnedFd, BorrowedFd) are already in std.

There is the odd (genuine) security issue tbf. But they are more of the variant:

“If an attacker is close enough to sneak that on me, then I’m probably already screwed.”

Why are you hallucinating facts?

• There is no “team of 200 rust developers”.
• “<lang> developer” is not an identity.
• uutils is not a “professional” project, as in people are paid by the (non-existing) uutils company to work on it.
• The project started as personal hobby of one person during COVID, There were no 200 contributors who sprung up magically and simultaneously from the start.

They wanted to avoid the “politics” and are not entertaining comments or explaining their decisions. It’s not up for discussion.

If you think you saw a group of 200 people starting uutils and doing this. You should seek medical help.

The “reported upstream” link is broken (fixed link).
