Different cases accept different types. Not always we can say that only one specific type is accepted.

"list +" accepts only lists, "list +=" is a syntax sugar for list.extend and accepts any iterables. "bytes +" and "bytearray +=" accept any objects that support the buffer protocol. "array +" and "array +=" accept only arrays.

Changing semantic is out of the scope of this issue. I think there are reasons for current behavior.
