syntactic sugar. In fact they want one good way of writing expressions.
The lack of these operators makes the source code more readable.

+= just saves some space and typing time.
Your editor (given it is powerful enough can easily) immitate
that piece of sugar for your and make it personal syntactic honey!

Here is my posted vim example:

|
|:map! += ^[:s/\([a-zA-Z_][a-zA-Z0-9_]*\)$/\1=\1+/^M:noh^MA
|
|Where   ":" means go into vim Commandmode
|        "^[" means Esc, you have to enter it pressing Ctrl-v and then Esc
|        "^M" means "Return', you have to enter pressing Ctrl-v and then Return
