> We already did that for core::string_view, why not do it again, the procedure has been a smashing success and of enormous benefit to everyone.

Can confirm. I am very enthusiastic about having this—https://www.boost.org/doc/libs/latest/libs/json/doc/html/ref/string_view.html—in Json docs, rather then just linking to a page in Core's docs such as what I did here for Container: https://www.boost.org/doc/libs/latest/libs/json/doc/html/ref/storage_ptr/operator_star.html. I was in fact so enthusiastic about it, that I have asked to make the type public (https://lists.boost.org/archives/list/boost@lists.boost.org/thread/FZRC6VSGV6MW2NGOAK3HCHOFCIYUUNVY/#BKM6JWZKDCMMTWOIYTW2TEZO7YRATPB3). Url's and Charconv's maintainers decided to not play along with the charade and reference boost::core::string_view directly with the obvious drawback that that type is not documented anywhere.
