You sort of answered your own question. People's workflows tend to morph around the idiosyncrasies of their tools. There'll be somebody doing something weird like using LF to keep lines separate for Linux but wanting them condensed to fit on one screen in Notepad. Notepad does preserve LF characters, just doesn't display them, so you can think of it as a no-wrapping display mode.

More practically, it could be as simple as checking whether text files actually have CRLF line endings. That's one thing I personally use Notepad for.

The hover text on that one is priceless.
