Agreed. It has started bothering me for authoring Markdown documents as well, where it’s often impractical to avoid monospace.

I like monospace for writing Markdown. I can't point finger on why exactly, but it feels like a manuscript or something. (Although iA folks have quantified this a bit: https://ia.net/topics/in-search-of-the-perfect-writing-font)

Conversely, for reading Markdown, I prefer a rendered version in a proportional font.

Some Markdown editors defaults to using a proportional type face for body text. Quite nice! Typora is one of them, there are probably others.
