If the whole thing were egg-shaped, you'd need to have every piece custom built depending on where it is, which is MUCH more expensive. Good non-aircraft example of this logic is in the design of the famous Sydney Opera House. As crazy as it looks, each section is actually cylindrical, so the same panels can be used anywhere on its surface (with minor modifications at the edges). | |

So you have a % of drag reduction on a small % of the fuselage where the whole fuselage accounts which account for a % of the total parasitic drag which, at best efficiency, account for 50% of the total drag. It is not a negligible but a very small advantage. And that if the nose is really clean. | |
