I’m 6’7”. It makes a difference. On most flights I don’t worry about it because I arrange to be in a position where I have more room or can fold my legs under the seat (people sometimes get upset when my feet reach all the way to the kick bar under their seat for some reason), but if I’m stuck in regular economy in a middle seat, I could be inconvenienced or even injured by someone reclining roughly.
