No no, do forget about it: like += for lists, |= mutates “the dict”, which often makes for awkward bugs.
And like += over list.extend, |= over dict.update is very little gain, and restricts legal locations (augmented assignments are statements, method calls are expressions even if they return "nothing")
Don’t forget the in place variant!

The |= does exactly what it says on the tin. How could it not mutate the left side of the assignment?
