Hello; I also don’t see this as being useful but if you did want to suggest it, you should make a ticket in GitHub here for the Haiku Depot Server and here for the desktop application.
Note that short-term if you do want this information, you can run this from a Linux host or a Haiku system with the curl and jq commands installed.
curl -L "https://depot.haiku-os.org/__pkg/all-haikuports_x86_64-en.json.gz" | gzip -d | jq -r '["package-name", "rating"], (.items|sort_by(-(.derivedRating//0),.name)|.[]|select(.derivedRating)|[.name, .derivedRating]) | @csv'
