This is more evidence to me that <xmp> needs to not go away, I know browsers are considering it and I really hope they don't go that route.

I use <xmp> for html code commenting - see the source code at https://elementcss.neocities.org/

The one thing these markdown examples are missing is a way to do grids! I bet there's a clever way to make columns and rows work.
