Automatically deriving Clone is a convenience. You can and should write your own implementation for Clone whenever you need it and automatically derived implementation is insufficient.

The Rust community is very adamant as a general thing that "you're holding it wrong" when people complain about e.g. BDSM passing semantics, but it's also got REIR/RIIR, which is kinda like "you're holding it wrong" for programming.
These two things together are a category error.
Whether this is a first order good because Rust's choices about how to split the difference between C++ and Haskell are in fact the best future for software or because they make all the money from Rust jobs and books and teaching and shit is one of those assume good intentions by default but also pay attention to conflicts of interest scenarios. Speaking for myself I think most of the zeal is legitimate with a few people trying to cash in like you get with any community.
But like all philosophies of the "There is One True Way, All Else Must Conform" stripe (in Christianity this is Opus Dei and things like that, in Islam it's called Takfir, it's not a new thing) it's misguided and destructive no matter how genuine the intentions of the hardliners.
edit: people will try to say that I'm uniquely antagonistic to Rust, but I opened the meme bookmark tab for a diff and saw this within like two minutes of writing my comment, it's a known thing: https://impurepics.com/posts/2023-03-24-refactoring.html
I call bullshit on this. If you can show any quote that could even be misconstrued as wanting some kind of language supremacy over every other from anyone in a position of "leadership", I'll eat my hat.
There's an "internal" community document entitled "The Core Team Is Toxic": https://hackmd.io/@XAMPPRocky/r1HT-Z6_t
There's an entry on the tropes page about it: https://enet4.github.io/rust-tropes/rewrite-in-rust/
You're trying to make the case that this is a fever dream hallucinated by me in isolation? Like I took a bunch of fucking mescaline and imagined a world where the Rust community is actively trying to get things rewritten in Rust, get the DoD to mandate Rust for whole classes of taxpayer funded software, the groups at the FAANGs doing strategic rewrites of like revision control systems that worked fine, the whole thing?
I just, made it up?
You started at
> it's fairly common knowledge that the Rust community leadership regards all other programming languages as existing in an adversarial, finite-sum outcome space with any remotely adjacent programming languages and regard it's elimination of other language use as a first-order good.
and now arrived at "there's a subreddit, a glossary entry for a meme and a blogpost complaining of the years defunct core team". Note that the complaints on that blogpost have nothing to do with what you're concerned about.

You seem to be conflating "projects using or recommending Rust" with "a grand conspiracy of a shadowy cabal of Rust people getting their way, all the way to the top of the US government".
I'll restart my claim: no one in leadership can be quoted saying that people should only use Rust everywhere. I'll go as far as saying that it's unlikely anyone that has a commit in rust-lang/rust (a much lower bar) can either.
But I didn't say that, I said you will get various degrees of transparency depending on where you're hanging out. Which is a related statement to your hedge.
But this kind of nitpicking is tiresome. I posted threads and links and stuff to a mountain of "everyone fucking knows this".
Everyone hates you guys, I'm just crazy enough to say it out loud even though a bunch of my recent posts are all going to get 4 downvotes in the first hour.
