I find it interesting that the changelog for the doc refers to removing guidance for the use of em dashes in 2024.

I tried tracing the history back in Github, and it seems that the intent was to prohibit the use of em dashes in normal prose:

> In technical content, use a dash to show a range. Otherwise, use a colon or other suitable punctuation. Do not use em dashes.

Anyone know why this was removed? It matches my training as a public-school student in the US, including in college while working on my Bsc in the natural sciences.
