When I had the front bumper replaced on the Mazdaspeed five years ago (or six? Can't remember), I had the hood re-done. It had been clear-bra'd since new... like literally two days after picking the car up from the dealer, we had the film installed. So the film was on the car for four or five years and 140,000 miles, and it came up without issue. On a Mazda... notorious for poor paint adhesion.
It's a non-issue. Razor marks might be an issue, though it's something you should discuss with your installer. If you or they install a pre-cut kit, a razor is not used. If the car is "wrapped" (not something I recommend) then maybe it is? You would want to discuss this with your installer. None of you guys keep your cars long enough for this to matter anyway
