Ever bad language feature gets used eventually. This is doubly true for frameworks where not only are bad features used, but also unintended and hidden features. Even if I know when to avoid 2-way binding, there is a high likelihood that someone else does not or does know, but adds a TODO because they "didn't have the time" to do it right.

In my view, the best solution is to (as far as possible) eliminate questionable features from the framework and enforce good practices.
