Yet many projects don't use them.

Sometimes they are wrong (as they are more like a comment than a compiler directive).

My first task in any project was to figure out why devs don't have error highlighting on for bad types (often it's "it was red so we turned it off"), but good luck forcing others who don't do type hunting to start doing it when "it slows us down".

I guess I'm spoiled in that I've done both Python and C# throughout my carreer.
