I do not find it comfortable reading lines of text that are that long.
As it is, I have margins on my Scribe set to maximum and have increased font size a bit from what I use on smaller screens, just to make it more readable. So I find this quest to reduce margins on Scribe rather strange. At very large text sizes, it would make more sense, of course: you'd want to get lines of text to be long enough.
