Well, using print over debuggers is fairly common in Rust and other languages with strong type systems because most bugs are, due to the extreme lengths the compiler goes to to able to detect them even before running the program, just lacks of information of the value of an expression at a single point in the program flow, which is where dbg! shines. I agree with all the other points though.

Anecdotally, I was just writing a generic BPE implementation, and spend a few hours tracking down a bug. I used debug statements to look at the values of expressions, and noticed that something was off. Only later did I figure out that I modified a value, but used the old copy — a simple logic error that #[must_use] could have prevented. cargo clippy -W pedantic is annoying, but this taught be I better listen to what it has to say.
