Suggestion: Add a feature (toggleable in the config) that makes it so only piloted crafts take damage from TNT, explosions, and fire. This will also ignore worldguard regions if they have a specific flag (could be added in Movecraft-Worldguard). I'm not sure about the implementation but I was told it wouldn't be too hard if I integrated it into MCC.
