I might be inclined to buy this complaint if tokio was part of the standard library. But it isn't, and I just can't see how its mere existence and tree of dependents has a negative effect on the "ecosystem", it's not preventing anybody interested in "embedded stuff" from producing high quality libraries that are not dependent on tokio, and I don't buy that there is some fungible mindshare being taken away. This to me seems more a gripe that Rust is not being adopted quickly enough in certain domains, which I believe has far more to do with both reasonable and unreasonable inertia.

(How is tokio fundamentally different than boost.asio and beast in this regard?)

I have hard time understanding how this "trail" of stuff (evoking imagery of pollution) that no one is forced to depend on nor is promoted in any special way in the core library or language is any meaningful impediment to developing and distributing libraries more appropriate to the embedded domain, but perhaps one can explain how.
