I'm sure the goal will always be to be as good as humanly possible out of the box. 99.999% of users will probably never have to think about it. But if your mission-critical application just happens to hit a case which the default behavior handles poorly, would you rather: 1) redesign your system and hope that a different design just happens to not hit the same bad case, or 2) tweak a knob until the GC fits your use case?

I think I'd prefer 2. But 1 will always remain an option I suppose.
