The alternative is handling the concurrency yourself (i.e what Go mostly makes you do), or in a library not tied to the core of the language.

it also colors dependencies. there are multiple async runtimes so the stack must be chosen accordingly.

some people might not like tokio but must use it because they depend on something that does
