It's not a big deal to have them cut the protection wrap out from over the sensors, that's what they did to mine a couple weeks ago when I had it done. I watched them do it, it looked very simple.
And if I had my sensors covered and not cut out by someone, I'd go back and have them cut it out. You've probably paid plenty enough to get them to properly cover your car, it's not worth the possible degradation of the sensors and finding out the hard way, damaging your wrap job and your car!
