Honestly, I wouldn't worry about it until you have a damaged hanger. As mentioned, minor bends can be re-aligned usually more than once. Just retired a 25-year-old alu frame that had its non-replaceable hanger re-aligned at least 5 times in its lifetime before the headtube developed cracks. Ride and enjoy until you actually need a replacement. It has already survived 15 years without damage.
