I spend a lot of time adding new items for en wikipedia articles on humans. To do so, it is necessary to search for items having the same name. Pretty much all such searches will pull up one or several ORCID person items, or CBDB person items, since these have been added in tens and hundreds of thousands. Because these have no descriptions, it is necessary to waste time inspecting each of them to find out they are not the footballer/politician/whatever that I'm searching for. Adding descriptions including the ORCID ID provides a means of disambiguating this item from that item, within the search results, without having to waste time calling up the full item. For the majority of ORCID items, ORCID is the only available property; for CBDB, the dynasty & CBDB ID. Clearly this is more useful than having a blank description. Clearly, also it's suboptimal and we live in hope that eventually better descriptions will be added.
You could always improve the description rather than being a griefer, Gerard. I mean, really, grow up.
