Now it's my turn to disagree. As an argument I have this thread [1], where similar discussion happened about flexibility of jsonb and throwing an errors (in this particular case whether or not to throw an error when a non existing path was given to jsonb_set). I can imagine significant number of use cases when adding a value to jsonb like that is desirable outcome, and I'm not sure if I can come up with an example when strictness is the best result. Maybe if you have something in mind, you can describe what would be the case for that? Also as I've mentioned before, consistency between jsonb_set and jsonb subscripting operator will help us to avoid tons of question about why I can do this and this using one option, but not another.
