Right now, in the page Special:Packages defined by the Page Exchange extension, the URL for the website of any package shows up as a link, with the link text being just the English word "Link". This is doubly bad: the text is hardcoded in one language, and the word "Link" itself is not too helpful, regardless of the language. Instead, I think it would be better for the link text to be the domain name of the URL. That is, if the URL of a package is https://example.com/ABCDE.json, the link text for it should be example.com.
Note that this should only apply when it's a short link: when the user views a single package, the full URL of the package is displayed - which is good.
