This is defining a common identifier without prefix.
So it will be forbidden to use addr_bytes as variable name.
I understand you are trying to keep compatibility with both structures,
but the drawback is really nasty.
Is there another solution? Or at least, we could mark it as deprecated and
remove it in release 2.1.
