I can definately see what people are concerned about regarding the topic. Some of Obsidians past games have not been up to snuff polish-wise. However, one could argue that this should not be attributed to poor effort from the company, but instead to publishers demands that the game should be released at a certain time. Not totally unlike how people are arguing in this thread.
If the employees at Obsidian as professional gamemakers can justify the extra content, and if their case holds up to scrutiny from the backers (e.g us) I see no reason why stretch-goals should not be had. I simply require that Obsidian put forth good reasons why I should care about getting extra content into the planned game. As long as they are confident that the end result will be a superior game then I am all for it.
The addition of another companion or area in and of itself is in my opinion kind of meh. But in context of the overall product it may be a good thing.
In conclusion, we as backers entrusted our money to Obsidian and put our faith in their good judgement. If they think that they can pull off more content without sacrificing the overall quality of the game...well why not.
I probably forgot something. But I hope the point gets through:) So I say no unless good reasons are presented.
