Not necessarily. Just now for example Apple is facing a regulatory problem with the eSIM, so they mention that they have an actual regulatory issue. [1]
But for this translation feature they have not even mentioned any regulatory issues, so we should from conclude, from previous and current behaviour, that Apple is delaying for something else. Probably engineering or political reasons.

Delayed approval and disagreements about the fundamental nature of what's allowed are two totally different things. Not sure why this example is relevant at all.
