We discussed the topic of fixing bad bindings vs. keeping backwards
compatibility during last week's Linaro Connect.

The main outcome was that we need to have a better review for new bindings
getting merged to avoid this situation in the future, but the general
consensus seems that bindings that are already in use but were never
reviewed properly (which should have caught this) should be changed.
We will likely establish an annotation in the binding soon to mark those
that can not be changed as opposed to those that are not considered stable
yet.
