Rust has a too-small stdlib because they want to avoid a calcified stdlib like C++ and Python, which both have too-big stdlibs.

This is a law of nature, your stdlib can either be too small or too big. It cannot be the right size. At least it isn't C.

I think you’re right with regards to the intention — but I’ve personally not experienced the case of an std lib being too big — good examples of “the right size” would be Go or Zig.
