There's one matter with assuming that void[] may contain pointers (which is not the case for something read from a file), so possibly ubyte[] is a more accurate type for describng raw bytes.

I see no reason to return void[]. The concept of a file is a sequence of bytes, not a sequence of voids. Yes, you might want to cast the file content's to various other data formats, but I fail to see how void[] is better than ubyte[] in that regard.
