The notch is just a temporary workaround achieved by sacrificing aesthetics (landscape mode eyesore)
If the sensors get their size further reduced in future, they can be placed on the outer rim of the phone, thus negating the need for a notch.
And there is no shame in putting small bezels on the top/bottom of the phone to accommodate the front facing sensors. Just throw in stereo speakers and a headphone jack, and most will be happy.
For man-made stuff, asymmetry is never beautiful.
