Yeah, seems like some things were a bit rushed (async) because there was a worry about marketing and adoption -- worries that I think most of us will agree should have been lower priority.
But we also know that things to do stdlib to die, right? Python is a famous example; almost every Python dev I know never uses the builtin HTTP client APIs.
So eh, I am okay with having de facto standards in the form of widely accepted libraries.
On a separate note, I had really high hopes for Rust 2021 edition. They had a chance to introduce new syntaxes and address error handling at least but they opted not to do so. Disappointing.
Stdlib works on every platform the language targets, third parties is anyone's guess.
When I have Python installed, I can be 100% sure of what works, regardless how uncool the library might happen to be, so those builtin http client libraries will be used.
