Why?
Its not like you're using the laptop camera for photography, but rather mostly video conferencing. I don't see any advantage that a 4k facetime camera provides.
I'd go one step further and say I wish Apple had a CTO option to "delete camera." I don't use the camera myself and see it more as a security issue than anything else. I don't go crazy over it and tape it up but I still wonder from time to time given all the crazy spyware stories.
