Of course it can be done, but the reason it's probably not been done is that it saves one button press, and in turn doesn't really improve anything as show credits vary too much. If your show has 2 minutes worth of credits are you going to wait 1 minute 40 seconds because you don't have the remote handy? Easier to just skip forward a minute and press watch now. I can't be bothered arguing about it, in my opinion it solves nothing, but if you want to try and get it implemented then good luck.

Some people, like my mother and aunt, are older and can't move around as easily as younger people. So reaching for the remote or keyboard to make that "one button press" every 30 or 40 minutes can be difficult. So yes, they do end up sitting there waiting for the credits to finish and the next file to play. 
You don't feel the need for the function, fine, but I and many others would like the function. So if you don't want the function, or have anything productive to suggest regarding the issue, why even comment about it at all? Go watch your credits, and let those of us who would like the function discuss it and try to find a way to implement it.
