My issues are with 'bytes', not 'bytearray'.  'bytearray(10)' actually makes sense.  I certainly have no problem with 
bytearray and bytes not being exactly the same.

My primary issues with bytes is not being able to do b'abc'[2] == b'c', and with not being able to do x = b'abc'[2]; y = 
bytes(x); assert y == b'c'.

And because of the backwards compatibility issues I would deprecate, because we have a new 'better' way, but not remove, 
the current functionality.

I pretty much agree exactly with what Donald Stufft said about it.
