But can't cautiousness occasionally be a good thing - particularly in games where Aggro control and damage mitigation are much less powerful than WoW?

Any way we slice it, not keeping the tank topped up reduces the buffer your group has between "Yawn, things are fine..." and "Oh Crikey, PANIC!".
Sometimes it doesn't matter that this buffer is reduced. Sometimes it does.

Unless your healer's Cure 1's are ridiculously powerful, there's no wasted mana in keeping the tank's HP bar at, say, 80% rather than 50%. Obviously that's an extra 30% buffer.
The Healer doesn't need to heal the Tank's every little scratch - just throw them a Cure 1 every time they're sure the HP granted from it won't overheal.

Tank and Healer Opinions will vary as to what constitutes a "safe" buffer for the type of content they're currently running. But generally-speaking a group will get the best results when the Tank is kept well topped-up unless there is a very good trust relationship between the Healer and the Tank. As another poster mentioned earlier in the thread, even on lower-difficulty content, keeping "more buffer than you need" can help because it raises the number of foes a tank feels comfortable herding for AoEs. (A good Tank generally sees their role as attempting to manage aggro for the entire team. This makes them naturally cautious, and unwilling to engage more enemies than they're 100% sure the team can manage...)
