be a breaking change.

   > Hi @shahar1, great proposal, thanks for digging up the precedent. One 
implementation detail: if we define it as `unwrap_single=True`, we can't 
distinguish "omitted" from "explicitly passed True", so we can't emit the 
deprecation warning only when the parameter is not provided.
   > 
   > How about putting the deprecation warning under the `unwrap_single=True` 
block?
   
   
   You could let it to be optional (`None`), and if it's `None` (i.e., user has 
no set it explicitly) - then set it to True + raise a FutureWarning (there's 
another PR that implemented it, feel free to take inspiration)
