Pretty much this. If Twitchers and Youtubers are save scumming who cares? Companions are very important to many people, and the fact that they can't die means I actually use them in Fallout 4 because I want to experience their stories.
If I fail a speech check because my Charisma is too low there's always another way around; the quests are designed that way (and it's fun to find other routes). If a companion dies it's the end of the road for their story arc. If I fail a speech check it's because of my characters skills (and a little luck). A companion can die through no fault of the player.
All in all I don't have any issue with the situation you are presenting here. But hey, that's just my opinion.
