Hey everyone I haven't posted here in forever I'm sorry

Anyways...I have a Jimmie Vaughan signature Fender guitar and where the screws screw into the tremolo cover plate there are three cracks very small but they are covered by the tremolo plate. So I was just wondering should I leave them alone or can they possibly get worse as the guitar ages and if I do need to do something what can I do? I hope someone can help me out with this matter I would greatly appreciate it. Thanks in advance!
