> Under the hood, the foundations for web filtering support has also been added — a backend service that can enforce content filters for child accounts once the user interface is completed in future updates, allowing age‑appropriate web restrictions without breaking web security or relying on curated lists.

I wonder if this is specific to Epiphany or if it's across the board for the user. If it's just for epiphany I think it's interesting that it would be one of the first "advantages" to using it over firefox or some other browser, at least for your children. Until now as far as I'm aware it has just been a pretty, though unfortunately rough performance-wise, browser with limited extension support.

Edit: Also this might play into the looming age verification laws spreading around the world
