AffectedPagesFinder should take the new description usage (D) into account when identifying relevant pages for a change.
This is needed if we want to stop also tracking all (X) or other (O) usages along with statement usages.
This probably requires T113468: [Task] Use compact representation of diffs in EntityChange. to work.
Note: Size of this task is estimated as Small in the assumption that T113468 is not required to fulfil this (this is what @daniel and @thiemowmde claim).
