You are right, I have used this in the past for links that I didn’t want to show up in the graph view.
But stopped doing this because renaming a note led to a broken link.
@Hexspa, if for some reason Obsidian will no longer be maintained there will be another app/tool/editor that works with the same kind of wikilinks, or there will be a way to convert all your wikilinks to markdown links.
