That's one use case we should capture. However, as I mentioned upthread,
such reporting/rendering can start way closer to home by looking at
client-side contribution. That's not something that needs to weight for an
IETF defined HTTP Field.

Failure to provide client-side reporting risks creating a perverse
incentive to push more work onto the client, which is probably worse from a
net perspective.
