An obstacle is: TLV-TYPE number of ForwardingHint and Preference fields are both 30.
This is valid from protocol point of view: TLV-TYPE numbers of Delegation and Preference are unreserved, because they can only appear inside ForwardingHint or Data/Content payload.
The difficulty is in implementation: ndn.lua currently uses a TLV-TYPE lookup table independent of parent element. It cannot distinguish that a 30 under Interest is ForwardingHint but a 30 under Delegation is Preference.

With the removal of the Preference field and the simplification of ForwardingHint, this becomes vastly simpler to implement.
