Tony –

IMO, you are asking the wrong question. 😊

ASLA exists to support the advertisement of attributes which can be used in 
application specific ways.
In any particular deployment case, a given attribute advertisement might be 
used by one app, multiple apps, or all apps.
ASLA allows to unambiguously support all of these cases with a single 
advertisement encoding format.

The correct question to be resolving here is indeed the question which has been 
discussed in an earlier thread: Is Generic Metric a link attribute which can 
have application specific use cases? I think the question to that is 
unquestionably β€œyes”.
That should be enough (IMO of course) to close the discussion.

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?
