It could be implemented by adding the fields to package-objects.
nitpick, those are records in guile scheme.
Did you mean to correct my use of "object" here?
Your are right about that.

Scheme Syntax: define-record-type type
(constructor fieldname …)
(fieldname accessor [modifier]) …

I finally begin to understand all these words an Scheme-ways of doing things.

Have I understood correctly that we have at least 1 nested record types in guix? E.g. the package record contains an origin record and a lot of other fields.
The rationale for adding screenshot-url to the recipe is that this parsing of wikidata->en-WP->url-for-first-image
for every package in our list is quite expensive. Better to do it once and perhaps update all the screenshot-urls
once a year or so.
I think the screenshot-url field will not be very helpful that can be
fetched based on wikidata identifier.
Ok, I understand your point.
