InputFilters are better suited for making/limiting changes on Editables
https://developer.android.com/reference/android/text/InputFilter.html
With TextWatchers, we're needing to control flow in difficult ways, as having to bypass the execution of some watchers with isTextChangedListenerDisabled for instance, or marking specific spans within the text so we're able to flag what's about to change and what not.
We’d reach a higher level of predictability by replacing TextWatchers with InputFilter-based listeners, and making sure each processor (currently a TextWatcher) is executed in the same order each time. This ensures a state A -> process P -> state B dynamic is known and repeatable.
