I'm unsure how useful they'll really be honestly! In many situations its very useful to know when your "done" talking with an NPC when they start repeating lines etc...

It would require a completely different design to video games. Current video games are designed around streamlining content. As a player, your job is to extract all content from an area before going to the next. That's why most areas are designed as linear corridors so that there is a straightforward progression, and most NPCs interactions are meant to offer something meaningful so as to not waste the player's time.…
Wrong right from the outset. Some games are designed around content and "extraction". Many are not.
