I think what Thiago means and I would agree with it is that QtCore has all functionality to implement any ::bind variations you may want.  Actually initial post already offered one of the possibility.
I’ve done couple of very similar thing in different projects but tbh they all have some specifics, like you mentioned - singleton for connections etc. 

So I think that in general it’s useful but I doubt it should go into QtCore API as its either become too broad or will have too many constrains.
