If you are using Typst to edit a document and you "refer to" later or earlier sections – it is definitely lifesaving if you move text around, helps keep track of repetitions, causes errors if you remove the section and helps the reader avoid scrolling/searching through the text. It also adds polish.
Definitely a must if you're e.g. writing a thesis.
Example:
== Section 1 <banana>
== Section 2
#link(<banana>)[In an earlier section], we elaborated on...
