The entire reason why I dumped my iPhone 7 is that it can't keep up with the current version of iOS, and I needed something that could. So, I'd always be stuck on a device with a back rev version of iOS, and after a short while, security patches would stop being back ported.
Moreover, my employer requires that I use a device that is running the latest version of iOS and is fully patched, so the iPhone 7 is now simply a non-starter.
As for using it as a webcam, the camera and other hardware is old enough that I don't think I'd like it for that use, either.
So, it'll sit in a closet or on a shelf until I decide what to do with it, along with all the other old iPhones I have, going all the way back to the original iPhone.
