IMO there is no need for this draft to exist.

Before a need for such a draft can be established two things have to happen in the following order:

1)There has to be WG consensus that application info such as VTN should be advertised by the IGPs.
To date no such consensus exists and there has been significant resistance to doing so.

2)If such consensus is reached there is already a defined/implemented solution - RFC 8202. Therefore, the need for a different set of protocol extensions would first require WG consensus that there are significant shortcomings to the RFC 8202 solution.
No such consensus exists nor has any discussion on this point taken place.

If the authors of this new draft want to start by discussing point #1 on the list - fair enough. But the starting point for that discussion should NOT be this draft. Therefore, I will make no comment on the content of the draft.

Authors - if your response is to try to explain to me why this draft is needed, then you have not understood what I am saying.

>    and other types of application-specific information to minimizes the
>    impact of non-routing information flooding on the routing convergence
>    and stability.  Due to different flooding information has different
>    requirements on the flooding rate, these multi-flooding instances
>    should be given various priorities and flooding parameters.  An
>    encoding format for IS-IS Multi-Flooding Instance Identifier (MFI-ID)
>    TLV and Update Process are specified in this document.
