rationale behind the design principle is the only organizing entity here it seems.

It is worth pointing out however (for “non-techies”) that Rust projects have been written by people who love Rust and use it as their main language, love it but can’t use it a lot in their employment, like it or are lukewarm about it and used it once or write in it on occasion, don’t like it but wanted to experiment with it, hate it but learned it because it could be beneficial to them in some way, hate it but had to use it (usually as a part of their employment).

The success of the language means that not everyone who uses it necessarily even likes it. So not even a “belief” in the design principle can be assumed by all involved.
