I’m aware, but even there the line between Scots and Scottish English is a pretty blurry distinction. It almost means “Scottish where I can only usually figure out what word that was” more than anything. Serbian and Croatian from my example are even closer than that, very much like Scottish and British or American English, with the main distinction that separates them being just whether it’s written with Latin letters or Cyrillic.

It’s a bit like if there was no Scots language, and the people in Scotland just still used runes to write but spoke the same language, except with even more old animosity fueled by previous governments.
