I am doubtful that even WG21 as originally constituted would have accepted I/O Streams with its "Look at me, I've got operator overloading" operator abuse if it wasn't Stroustrup's own code. If some outsider had come along and said "Look at this slower, clumsier, operator abusing alternative to C's stdio" the committee might have quoted Stroustrups' own words condemning such abuse. "the ability to define new meanings for old operators can be used to write programs that are well nigh incomprehensible".
I'm with you up to a point on overloading, if it were up to me for example Rust would not implement Add and AddAssign on String, and certainly Java wouldn't special case += but we are where we are.
However Rust has several operators (fewer than C++ but still several) that aren't just for arithmetic types. Deref and DerefMut of course (used to implement smart pointers such as Arc), Index and IndexMut (for the indexing operator []) but also Try (implementation of the ? operator) and (though rather more distant into your future than Try if you write Stable Rust) the Function operator traits Fn, FnMut and FnOnce which represent callables.
Of course arguably Rust isn't overloading operators at all. Rust has no subtyping, and so whether you can Add or Multiply or Try something is a matter only of whether that type implements the associated Trait.
