Indeed.
Maybe it's a shame, maybe its not. One thing is for sure, the precedent was firmly set long ago and it's not coming back.
However, that doesn't mean wars cant have meaning again. Meaningful wars don't always necessitate a firm CB. Real meaning, not petty thirteen year old emotional girl meaning like "so and so from alliance X said mean stuff on the owf 8 months ago and our entire alliance will never forgive them for it" or ridiculous path of least resistance wars because "lolwhy not". Things can have thought, reasoning, and true pragmatic rationale behind them again, very easily. Someone just has to do it.
