An interesting read! However it seems they sort of talk beside a big point of "task ports". My example is not so much communicating with the outside world in a general sense but more communicating with the browser, using in Elm unimplemented browser APIs.
The responsibility would be completely on the javascript side to return a result, but right now the only way to call these API:s is to write "Native" code, or to make "dual ports", one for sending a command, the result of which is then returned in a subscription and need to be paired with the call without any guarantee of the order of the results etc. The question is, why is it worse to have a Task not return a result than to have this other mechanism not deliver a Msg? In both cases you'd get nothing. Especially if Native becomes Kernel and even more unapproachable (which in itself is probably a good thing), then we really need a way to have the user make Tasks, or something similar to be able to use the browser APIs. For databases, websocket-like stuff, http calls etc, that have internal state, then effect modules are probably better, but for calling a function to get some crypto random or to access LocalStorage? Seems like it's too much to create an effect module for that, just look at the code in my example above. That level of simplicity should really be available if people are going to be able to use browser apis productively.
