It isn't just this, because I can put my hand in front of my phone, or put my phone to my ear or put my phone face down and the screen does not blank on other apps or just on the normal home page. It does when you're in a phone call, but that must be app-specific. This suggests to me that Waze has explicitly selected this option, or at very least has not opted out of it. I don't have issues with any other apps I regularly use except waze, if my hand blocks the camera while trying to tap the screen, it blanks on me and it's really bothersome.
Your analysis isn't exactly wrong, but it is pretty much "just this". The proximity sensor is enabled on a per-app basis. If you have "wave" turned on for voice prompts, then Waze enables the proximity sensor, and as a side effect disables the screen when it detects proximity. So, you are correct that Waze has "explicitly selected this option"; they have done so in order to use the proximity sensor to detect your hand-waving. Other apps don't do this because they don't use the proximity sensor for anything.
If it is such a bother, turn off the "wave" option for voice prompts. Use a 3-finger tap if you must use voice activation.
