In the case of clerics in D&D, I think they have a deep knowledge of the expectations of their Deity. I wouldn't nitpick minor infractions. That would be covered by an occasional general atonement. I would though warn a cleric as DM if they are about to go off the deep end with their character. If they do then they are taking that hit because it is worth it for roleplaying reasons.The issue with power outages from a story perspective is you can never be wrong and not know it.
Take Claude Frolo from Hunchback. He thinks he's a worldy man of God, but he's not and that's where the character richness comes from. It'd be a whole different story if he started shooting blanks and knows god's upset with his actions.
And I'm not against varying that up. One example, I ran a campaign once where the Deity couldn't just give spells to anybody. There was training and mental discipline required to be able to accept high level spells. So in some situations a Deity might forego immediately taking away powers because the PC is part of the Deities plan and replacing him is not feasible. It did make the Deities more concerned at lower levels to be sure their clerics were faithful. You can't replace a 19th level cleric overnight.
What I am arguing for is the default should be what D&D has supported from day 1. Then the DMG should provide DMs with a whole variety of ways to change things up if they want.
