The main problem I often run into is not wrapping when reading code in an editor, but rather wrapping when reading side-by-side diffs, for example in a github PR or review board RB. You get not only double the code width, but also an extra 6 or so columns on each side for line numbers, plus margins and scrollbars; so 80-column text is really more like 180 columns wide that your window needs to be if you don't want any wrapping.

On my typical developer laptop a full-screen terminal window (which I personally never use) with a system default 11pt font is 202 columns. A modest bump to 13pt drops that to 176 columns, meaning I can't view a side-by-side 80-column wide PR diff without some line wrapping.

That's great that you have a 350-character wide display. Requiring everyone to have acres of screen space, either because they can afford a 34" monitor (or 2 24" monitors) OR because they have good enough eyesight to be able to use a microscopic font is excluding a lot of people.
