TNT Explodes gamerule doesn't stop /summon

Original Description:
Turning off the TNT Explodes gamerule will remove any ignited TNT lit by a player as soon as it was created. But if you use a command to summon TNT ( /summon tnt ) it will be created and after the fuse runs out, will explode regardless of the gamerule. This creates a loophole that could be used for obvious malicious purposes.
