This comment indicates the problem! Taking the scare-quotes "enterprise" as a synonym for "bloat", one person's necessary feature is another person's bloat.
.NET is an interesting case, because of WinForms, which is a de facto part of the standard library. I think few C# developers think of WinForms as bloat; it's very convenient for making simple UIs. Yet putting, say, GTK+, in the Go standard library would doubtless be considered bloat. I don't think there are easy answers to these questions.
Agree, the "enterprise" jibe here is misguided - as an OSS developer, I find the dotnet standard library to be fantastic. I don't find it to be at all bloated or 'enterprisey'.
