This works to remove proof from the user's settings page but proof is still visible in other web pages. A quick look for proof shows that proof is tangled into the other parts of Froide.

This begs the larger question of should some parts of the new Froide not be include in UIPA? There are several new things besides proof such as campaign, geo location, etc.
