According to the Made By Google Twitter account, the company has added an option to hide the notch. It's not that it makes the notch go away entirely, according to 9to5Google; it's that it blacks out the entire status bar at the top, making the notch much less noticeable. It's not a perfect solution, as it basically looks like a bezel, but some may prefer it to the notch look.
The feature isn't yet available to consumers; it's still a developer-only option. You can see what the notchless bezeled Google Pixel 3 XL looks like below, but the question remains: Is it better or worse than just embracing the notch?
