Easily, just look at the standard libraries of Java/Python and Golang! :-P
To get one thing out of the way: Each standard library has dark corners with bad APIs and outdated modules. IMHO it is a tradeoff, and from my experience even a bad standard library works better than everyone reinvents their small module. If you want to compare it to human languages: Having no standard library is like agreeing on the English grammar, but everyone mostly makes up their own words, which makes communication challenging.
My examples of missing items from the Rust standard library (correct me, if I am wrong, not a Rust user for many reasons):
Cross platform GUI library (see SWING/Tk)
Enough bits to create a server
Full set of data structures and algorithms
Full set of serialization format processing XML/JSON/YAML/CVS/INI files
HTTP(S) server for production with support for letsencrypt etc.
Things I don’t know about if they are provided by a Rust standard library:
Go like communication channels
High level parallelism constructs (like Tokyo etc.)
My point is, to provide good enough defaults in a standard library which everybody knows/are well documented and taught. If someone has special needs, they always can come up with a library. Further, if something in the standard library gets obsolete, it can easily be deprecated.
