Speaking as WG chair:

We had a protracted discussion of the usage of link attributes for multiple 
applications. The outcome was RFC 8919 and RFC 9820. If you browse the ospf and 
isis WG archives for the years 2015-2018, you’ll see there was lots of 
discussion. You can also view the IETF meeting materials for these years. This 
is not open for discussion.

Thanks,
Acee

Subject: Re: [Lsr] Generic metric: application-specific vs 
application-independent


FWIW, I think that this is the wrong question.

I think that a better question is: Is there a usecase that is so overwhelmingly 
compelling that the added complexity of ASLA is warranted?

WG,

   Generic metric as described in 
https://datatracker.ietf.org/doc/html/draft-ietf-lsr-flex-algo-bw-con
   can advertise multiple metric-types and values and be used
   by any application. All the use cases that I heard from network
   operators while writing the draft could be solved
   using generic-metric advertised in an application-independent way.

   I am looking for clear description of use cases that would benefit from 
advertising
   generic metric in an application specific way. Can any one provide such a 
usecase?
