Well, in fairness, Ady did make plenty of changes in Star Wars that others might deem totally unnecessary, so other people suggesting new or longer shots shouldn't be a problem. Let's not forget that a vast amount of criticism aimed at Lucas over the special editions was for doing precisely that, changing things many people didn't feel needed or "should" be changed. Fan edits are no different to the special editions when put in context against the original movies. The only difference is whether the new stuff works or not. Some of the Special Edition stuff really does work, otherwise Ady would have removed it all from ANH:R.
