It is true that if you need to use Tokio, you'll end up using Tokio. That is not what was being suggested, though: it was just that tokio is not required for a simple block_on implementation. If you're already using tokio, using its block_on of course makes sense. But in that case, you're not adding "few hundred dependencies," you're using the ones that you're already using. And like, to be clear, "the few hundred dependencies from tokio" is also misleading. A `cargo add tokio --features full` adds 43 dependencies to your Cargo.lock at the time of writing.
