I see no reason why strictness would have pathological performance problems. If you don't need to compute a value, dinner compute it. No performance problems.
I also see no reason you would need laziness for 5% of programming problems. That seems absurd given that the overwhelming majority of programmers have gotten along without it for 50 years.
