What use would it have? The other languages mentioned (Chinese, Spanish, Japanese - I can't speak about Hebrew or Arabic) all come from very hierarchical societies that are still very hierarchical today whereas English has been seemingly on a mission to remove all such things for centuries, so thou was dropped for you by around 500 years ago and there's been a movement against honorifics like Miss or even the precision between the last few gendered words like actress.

Thus I'm not sure why this kind of detail would arise. in-law to a native basically indicates any of "they're not (really) my family", "they're not my problem" or "they poke their nose into my business when they shouldn't", or "I'm not going to share their name with you but I need some way to indicate a relationship". If the precision is needed it can be added later, like everything else in such a generalist (low context) language.
