The fact they’ve released this feature with a help page that directs you to a “I accept the risks button” is proof enough that this never should’ve been released like this in the first place.

The feature itself would be great if it were opt-in and easily manageable from the UI, but it was released long before that. Instead, they released a list they control remotely with no UI that’s opt-out and then went “we’ll put the user in control later”. This is exactly the user-hostile approach that Firefox users are sick of.
