But that's associated with a generic aero surface and the viscosity of a fluid and the speed of the flow of said fluid. This doesn't have anything to do with the characteristics of an aero surface. So even though Reynolds number is not a major deal, having a crappy aero surface is still a big deal, especially if you're trying to extract the maximum performance out of an aero surface and this is even more important when an aero surface is small.
If you look at verus engineering (makes some incredible aero parts) they try their hardest to keep the aero surface clean and mitigate screws and bolts to key areas to not trip up flow. They also try to recess screws when possible, and use extremely small rounded screw heads to prevent turbulence around the screws.
