I'm fine with them leaving this alone because 1) distracting someone with dialog is a thing - it does make sense in many situations, and 2) it's easy to not abuse it - I don't feel like I have to lose out on gameplay content. It's one of those things that can be abused to hell if you want to, but do make sense and have good roleplaying value when used in moderation.
Personally fixing it into more controlled mechanics would actually make it more uh rewarding and fun so it'd become less an exploit and more a proper part of the game.
