Hi Pavan,

No/do not support.

I concur with those who expressed their concern on the potential confusion
due to having two WG models (provided that this nbi-yang draft would be
accepted) for a similar purpose.

It would have been nicer if the authors of the two drafts would have had
chances to discuss for a potential resolution.

Augmentation of the VN model doesn't seem possible, however, as the VN
model is more particular model (i.e., TE model) than the nbi-yang model. If
my reasoning is wrong, please correct me.

One resolution I can think of  would be to combine the two models into one
single model. I believe this is still possible from a modeling standpoint.
This may result in some delay for implementation, yet this option might be
much better than having two standards models.

My two cents,
