Well I don't know... some automation could come in handy, like restocking the 50 or so spare boosters on my station for refueling, which I can only launch 2 at a time for... Or large ships built in 10 stages.
How to implement it and what limitations it would have is what would determine if it makes EVERYTHING easy or not. Say you had to build the first one manually, save the finished product, and have automatic re-assembly available for future copies.
I'm not saying I'd personally want that (yet.......) but I sure would consider the possibility.
