B737 MAX 8 First Officer conducting a post flight walk around reported the nose strut was at full extension and was concerned about the aircraft tipping on to its tail.

Narrative

As I was performing the post flight walkaround; I thought 'Wow; these MAXes do have a long nose strut.' Then I looked closer; and saw that not only was a lot of the shiny portion of the nose strut showing; but the scissor was almost completely extended; at what I would guess was a 160 to 170 degree angle. Having flown cargo aircraft prone to tail tipping; I am very attuned to the issue; and the first thing I did was look to see if anything unusual was being off-loaded from either cargo hold. Seeing nothing; I was wondering if I should have the forward crew stop offloading; when the aircraft visibly and fairly quickly settled back down onto the nose strut.I believe that the nose strut was probably at full extension; and wonder how close we came to putting the aircraft on her tail. I did not have time to take a photo or any measurements. Is the MAX 8 immune to tail tipping? Could it happen with a large number of large passengers aft of the wing while everyone forward has deplaned and the forward hold has been emptied? If the possibility is less than zero; it might be worth taking some mitigating steps to avoid a very expensive incident!
