Mines are static defenses placed by direct player action, and if they were left until a player action caused their destruction, I feel it adds depth to the world.

Keeping your max number of mines up, in useful locations, takes a dedicated effort... meaning players who intend to do it will be spending an awful lot of time in engy gear regardless. Forcing them to redo it should the need arise to swap out kits for a minute, to take a tower or something, seems harsh.

C4, spawn beacon type devices, router pads, any type of motion sensor... basically everything other than mines, need to disappear instantly on kitswitch or death, however.
