> This is why "1 space" is correct and two spaces conflates different layers of document creation (the textual information to display and how it is laid out)
The problem is that I know of exactly zero programs other than TeX and the descendants thereof that are able to reliably distinguish between word-spaces and sentence-spaces without being explicitly told to do so (e.g. with double-spaces), and even then.
There are indeed different space characters in Unicode, and if Word wanted to do this right it would autocorrect <space><space> to, say, <en-space> or <em-space> (the way it already does for quotes, much to the chagrin of people including code snippets in Word documents).
