The entire game design and physics of SC is built around "World War 2, BUT IN SPACE". I mean damn, they even have actual cockpit windows with no appreciable polarization (note the freighter pilot blinded by a simple laser scanner in the second video).

That said, missiles with proximity detonation only make sense if they're actually built to be fragmentation weapons, not pure explosive-based, due to explosion shockwaves being useless in space thanks to a lack of medium to travel in. And even for fragmentation they'd need to get really close due to inverse square law.
