I can’t imagine a reverse camera being a better alternative to looking out the front windscreen - sure it being a bit further forward then your seating position and wide angle might give it a bit extra visibility around close objects, but it definitely does not offset the advantage of a natural ~200 degree field of view - and that is before you move your eyes or swivel your head. This is much much more valuable particularly for faster moving objects (which are a greater problems).

That said I may be biased because my current vehicle has rear front and side cameras so I get the best of both worlds!
