Why are void[] contents marked as having pointers?

I think a better design for that read() function is to return ubyte[].
I have never understood why it returns a void[].
To manage generic data ubyte is better than void[] in your program (sometimes uint[] is useful to increase efficiency compared to ubyte[]).
