That's true, but you cannot get 500 entities at once, it remains the problem that you have to do 1800 requests in my previous example instead of 4. Is this not a problem?

What are the recommendations of stewards/maintainers/owners of the codebase regarding the issues? Either workaround is not desirable.

I think this request was closed without addressing the issues reported in it.

@Lydia_Pintscher It's not the case. How can you download the _P131 property of 1800 items with only 4 requests? Either you have to do 1800 requests, or download tons of data you use for nothing. This would not be for my convenience, it would be better for Wikimedia servers and resources. Did you take into account?

Many Wikibase items have many statements. Many tasks deal with only one or few properties. It would considerably improve performance, traffic and load if it were a possibility to filter properties in the same manner as languages and sitefilter, especially when getting 500 entities at once.
It would be very useful to add a parameter properties or similar and allow values like P31|P1082|P939 to filter the returned data.
There is something similar for wbgetclaims.

You can see it here:

select * from page_props where pp_propname = 'wikibase_item' limit 100

gives

{
  "batchcomplete": true,
  "query": {
      "pages": [
          {
              "pageid": 51046741,
              "ns": 0,
              "title": "Kofoworola Abeni Pratt",
              "pageprops": {
                  "defaultsort": "Pratt, Kofoworola Abeni",
                  "page_image": "Kofoworola_Abeni_Pratt.jpg",
                  "wikibase-shortdesc": "20th-century Nigerian nurse; first black Chief Nursing Officer of Nigeria",
                  "wikibase_item": "Q25796287"
              }
          }
      ]
  }
}

I suspect that there is a table with page properties. As I see, it is already integrated, just needs a magic word like {{WIKIBASEITEMID}}.

Magic words are not Wikibase client. This a Wikipedia pageprops. See T349571 for links. Could someone add the right project and assign the task?

@Pppery What would be the correct project? What project deals with the {{PAGEID}} magic word? This is not about Wikidata, this is about magic words and page properties on Wikipedia. No one seems to deal with this feature request since 2016. Could you help please?

I propose {{WIKIBASEITEMID}} magic word. Like {{PAGEID}}, {{PAGEID:page name}}. See also T349571.
