Hi Pengyuan,

1/ The issue in hand is not about whether there exist some fields in Interest packet format that one could abuse, but an architectural issue.
Interest is not meant to carry data.
Generally speaking an Interest packet is not secured (except those that lead to app state change effects)

2/ I'd agree that in a strictly local setup one could do whatever one wishes, but the resulting system wont be compatible with NDN in general, what is the point of pretending it is NDN?
