One reason to suggest a smaller max character count is to assist those with impaired vision. I'm highly myopic and, while my lenses correct for it, I still seem to get eyestrain when using the default font/sizes in most IDEs. Bigger-screen monitors counterintuitively seem to make this worse, not better.

I can only imagine that this would be even more important for individuals with more severe vision impairments.
