You're using "bug" to mean "thing I don't like".
Just let's stick to the examples we have here. How do you call Malkavians having copy pasted placeholder lines when all other clans have different lines? An intended feature? Okay, bug is a little bit much here, but it's clearly an oversight at least. Shouldn't this be fixed? Where is the line between real bugs and things that some people find okay and others don't? Or let's take the theatre exit. Obviously the mapper working on the tutorial map and the hub didn't communicate, so we have an area that doesn't fit into the city at all. To me this is a consistency bug, is this a cool feature to you? It doesn't affect the gameplay anyway, so to me this is a fix! If this is too much modding for you, as mentioned in the discussion here, you can always play the vanilla game today with just the exe and dll fixes of the patch...
Sure, maybe things would have been different if Troika had more time, but there's no way anyone can know what they would have done differently.
That is why it is called an "unofficial" patch. I can't know what Troika would have done, so I fix what I and the hundreds of people helping think should be fixed.
