Most color negative film has a similar latitude and XP2 is simply a one color, color negative film. Actually most 400 speed B&W negative film has a similar latitude for normal scenes.

This doesn't mean mean there's no point in metering, just that you have options if you need them.

And Yep, it's a great film for any situation where the ability to meter or set exposure is limited, like with toy cameras, without the need for development changes. This is how disposable cameras work too.
