> Two ('full') space characters were added because of (tele)typewriters and their fixed width fonts

I could never agree with this, because monospace fonts are already adding extra space with the dot character, which is much narrower in proportional fonts. That fact alone makes the visual gap already similarly wide as it would be in typeset proportional text. Adding a second space makes it much too wide visually (almost three positions wide). It looks like badly typeset justified text.

(I understand why people are doing it, I just don’t agree on aesthetic grounds.)
