I'm not sure I'm seeing your argument against using promises over observables for single events. Observables are a superset of promises, sure, but you can map them into situations where you'd use promises and then still have the flexibility of observables and all their operators. along with this you get the consistency of using the same async paradigm everywhere.
I find you run into trouble when you start mixing them. If you use observables for 0-N events and promises for 1 time events you're always converting between the two.
