In the end I'm +0.5 on | and |=, +0 on + and +=, and -0 on doing nothing.

While my "vote" is and should be much less significant than Guido's, I've explained why my initial expectation for dict+dict would NOT be the proposed behavior, but rather something "vectorized" similar to Counter.

Overall, I am +0.5 on do nothing, +0 on |, but -1 on +.
