Review Comment:
The underlying structure does not admit a null value. It is Protobuf, there
are no true null values (*this has changed slightly in recent versions but we
do not use that codegen option for this structure).
Let's be clear here, though. Is this for input, or output? I would be -1 to
ever returning `None` for this attribute. If it's merely to accept it as an
input on construction that might be OK, but it would be misleading to people
when it doesn't round trip.
