My quick search for casement windows at Lowe's (https://www.lowes.com/pl/Casement-windows-Windows-Windows-do...) didn't show a single one that has that feature.

They need to be:
1.) wooden 2.) vertically opening 3.) same style as the old windows
The windows the OP posted are 100% illegal since they do not fit the character of existing windows (wooden and vertical).
And it's not just windows: there are doors that work like that too.
And at night, during summer time, you can still create an airflow without letting your window fully open: so for thieves it's not as easy to get in as if you had let your window opened.
Honestly I take it for granted: I'm surprised when I stumble on a window that doesn't have that mechanic.
