No, not really or this conversation wouldn't have happened. There's plenty that's vague about a lot of D&D, including magic.
And people complain even about expected consequences, so who cares about that?
See the way I look at it is that they wanted to allow for something like a wizard's duel, where spells can be blocked or disrupted, as we've seen in all kinds of genre fiction. But they looked at how it was done in the past and realized how much it sucked, and so they decided to make it a reaction. I don't think that breaks the game or requires the fiction to be twisted to match the rules.
