Abstractly this is true, but software development is a human practice, so it matters not what's technically possible but what people actually do.
That's why the most important difference between C++ and Rust isn't some technicality even though the technical differences are huge, it's cultural. Rust has a Safety Culture and everything else is subservient to that difference.
Sugar matters, Rust's familiar looking loops are just sugar, it only "really" has a single way to do loops, the loop construct, an infinite loop you can break out of. But despite that, people deliberately write the other loops - and the linter strongly recommends that they write them, because the programs aren't just for machines to compile, they're for other humans to read, and a while let loop is an intuitive thing to read for example, so is the traditional for-each style iterator loop.
