Dont know what all the fuss is about. The scariest and most ludicrous days in F1 were the 1.5 turbo days. V8/V10/4 pot boost, who cares?
The cars will still go just as fast and will still make a ridiculous noise. Just more like a Group B rallycar than the current V screamers which cant be a totally bad thing.
The engineering challenge that the current engine configuration offers, will just be redirected into (lets face it) more accessable and useful technology. Performance capping will allow the lower teams to mix it with the big boys, whats so bad about that?
