I agree with that . Just map all the uint8[] to bytes[] instead of list[] may cause other problems since some algorithms are designed using the msg.data as list in python .

I still think that using bytes rather than list[byte] would be a good move (at least from IDL byte[] types, if not for uint8[] types). Yes, it would be a breaking change, but it would be a good breaking change and most dependent code would be very easy to update (and likely get a nice speed boost).
