Hey Tobias!
Where? It's neither here[0] nor there[1]. I found it on blogs.The name isn't that important; just don't change it for fun, and ‘longterm’ is what I'm used to hearing upstream.
Here, https://jxself.org/linux-libre/There is a table at the bottom of the page. The same naming convention is used by Trisquel as well.
Regards, RG.
