I wouldn't stress over it. Just change the HFT filter on the next oil change. What's your current oil change interval? We do a lot of riding and change oil 2-3 times a year at intervals ranging from 4,000 - 7,000 miles. Got caught twice without the HFT filter on hand and just skipped it, changing oil on a shorter interval the next time around. I've examined (without scientific instrumentation or knowledge) the used HFT filters after 10,000 miles of use and saw no obvious wear, deterioration or anything concerning. I've also rolled the dice and took changes by not changing the oil drain crush washer (flipped it over) and re-used the HFT gasket o-ring (was on back order). I would really rather not do these things but I'm not going to worry if I get caught short. I'll keep a close eye out for leaks, oil level and unusual performance in the meantime.
So, the risk is on you, but at 40,000 miles on this Dino there hasn't been any problems. I would change the HFT filter and gasket within 4,000 miles or no later than a year from now. Just my contribution, your mileage may vary.
