As a mapper: I waste my time adding/making skins and storyboards because it's the way I want the map to be played by others, therefore I agree with the decision of not being able to delete them.
As a player: Some specific beatmaps have annoying skins/storyboards that would improve my playing on them if I delete the skin/storyboard (examples here, here, here and here), therefore I don't agree with the decision of not being able to delete them.
I would say I'm neutral about this, but I'm not. Everything can be optimized and improved if we actually care and bother to do it, so people wouldn't complain that much about this. That's why SB Load was implemented and that's why there are some rules about sprites resolution and all that.
Exceptions? Yes, there are exceptions, but probably those are storyboards with a high amount of things going on at the same time (and most of them have usually a warning on the description).
Mistakes? Yes, there are mistakes, but we're all human and these kind of things happen.
ps: To be quite honest, I think Kiai Time lags way more than a storyboard and you can't delete that, but whatever xP
