You don't have to maintain a custom OS. You just have to be allowed to run your own code, then you can just write a simple webcam app and never need to fiddle with it ever again. You'd probably be surprised at how many developers there are today that do in fact maintain custom software for older rooted iphones, and given that I'm sure a lot more devs would release and maintain even more software if every old iphone under the sun was fully open. Not just the few still on the lucky iOS versions that have a jailbreak released but isn't yet patched.
