Look on the bright side your car weighs less now. I wouldn't worry about it. I cut the vents and painted them black to open up those holes. Leave'm be. Although if you want to give them a clean edge go and get some 1/2" rubber tubing. Cut a slit down it and slide it on the inner edges of the hole. Gives it a softer look without making it look like somthing is missing. If it falls off tough poo go and buy more tubing for a buck.
Hope this helps a bit
If they come back and steal the little black tubing I would worry.
You could goto Subaru and buy them for a low price of around $60 or $70. They over charge like crazy. You know that little rubber striping between the sideskirts and the car? $20 for a little piece
