You can always start modding 5 year after the game is released, like me... then spend 6 years on it figuring it will never be officially patched just for it to happen anyway.
ANYTHING CAN HAPPEN.
As for the Stream, my own modding experiences in mind yeah that can be boring to watch. And if chat is on, it can also be very annoying for the person being streamed. There's a lot of back-seat programmers around who would love to tell you all about how you do wrong and what would be a better way to do stuff.
Pretty much the only stuff I bring out to people cause it would be interesting to them and perhaps educational is a progression-of-cutscenes or things that went hilariously wrong trying to work on them. From the start, where nothing works as it should, all the way to till it actually works properly. Of course, this isn't exactly as easy for a full team that actual make content that's going on sale rather than a solo-person working though.
I would still probably be interested in watching one of the vids that is boring and all have already stated why it's boring. Education can't always be super-thrilling, and it can be rather interesting if it's your area of interest.
