In my 25 years of software development I've found that I'm rarely able to enumerate what an application should or shouldn't do on my own. Unless the app is extremely simple and has very few options it's incredibly unusual for any individual to understand everything about it. While I don't have a use case where I'd want to use a variable space font in a terminal, that doesn't mean such a case doesn't exist for anyone. Maybe some people want that feature.

Windows Terminal, for some reason, gives users the option to change their font to one that isn't monospaced, so I'd argue that it should render them correctly if the user chooses to do that.
