Good news! The camera finally seems to be accessible from a home screen web app in the first iOS 11.3 beta.

I have made a repo with a few files, which demonstrate that it works:

Steps to test:

1. Serve these files from a website accessible from your phone
2. Open the index.html in iOS Safari
3. Add to home screen
4. Open app from home screen. Now the web page is open in full screen, without navigation ui.
5. Press the file button to select an image from camera.

Now the camera should work normally and not be a black screen. This demonstrates that the functionality works again.

I must add that I use a plain field, not getUserMedia or somesuch. I do not know if that works.
