I put rigid carbon fork on my Niner Air Nine (turned it into a gravel road bike) and the AC is now smaller than it was with the 100mm fork and the slight geometry difference is not even noticeable.
Not necessarily but I wouldn't want to change my geo if I was comfortable on the bike and didn't want a more aggressive or upright position maybe. It is handy to keep in mind. I did almost swap a suspension fork both of 100mm travel but one had a significantly smaller A2C and it would have made my bike very aggressive in a way I didn't want.
