Since there are over 13,000 lines of recorded dialog, hopefully Bethesda took notes from Skyrim's http://www.nexusmods.com/skyrim/mods/23390/? and fixed it so that NPCs in Fallout 4 at least respect you over time and acknowledge your accomplishments. Especially once you've proven your PC to be a valuable asset. The last thing you should have to deal with is being belittled with the same static and looped responses from NPCs who are already very familiar with your PC's presence and accomplishments.
I don't expect all NPCs to kiss my ass, worshiping the ground I walk on. Though after achieving a high ranking position in The Companions, the last thing I want is to for city guards to still refer to me as a 'milk drinker'. Or when I slay a dragon in front of city guards and town residents, they acknowledge what I did, right then and there, though the next time I see them, it's like I never did anything and those same NPCs revert back to the same looped, static, sometimes still belittling replies.
I know this is a bit of a stretch, though It would also be nice if the gradual respect or acknowledgement didn't only come from completing quests or objectives, and also came from random occurrences like helping out city guards and civilians fend off a raider attack.
