I didn’t have a strong opinion on standard library sizes until I tried Rust, but Rust was not a very pleasant experience because there were not standard packages or even consistent community advice for things as pervasive as error handling or async.

But I understand people have different opinions and that there will never be a standard library that appeases everyone. I don’t think “having a batteries included library” aims to appease everyone either. But mostly I just don’t understand the people who criticize Go for not having enough things in their standard library because Go’s standard library is one of the more useful (which may not be everyone’s ideal).
