I like the one-way bindings myself, but one thing I've never reconciled with the one-way is the one-true-way view is that in a one-way only world you tend to wire up more event listeners to deal with data changes and inputs, and those listeners can be all over the place with arbitrary side-effects. A two-way binding ends up being shorthand for a specific type of event handler with a known side-effect, making them easier to find and reason about. Maybe I'm missing some other aspect to the one-way-only view though.
