We have not specified the use of the Object within the Open message! If there is a need to carry vendor specific information, then using the VENDOR-INFORMATION-TLV within the Open object is allowed. In case they have a need for the object within the Open message, please provide a usecase and perhaps it can be added in the draft! Hope this helps! Thanks!
