I think that a piecemal stripping helps to facilitate communication.
It seems like in a ton of the paladin threads, the story goes something along the lines of "and then my paladin did something. Should he lose his powers?" All the talk of crossing the line is moot if no one knows where the line is. Losing a power, or an effective level, or something less shows that you're near the line without having to have had to step over it.
I think that people, especially people playing with their friends, might have a better time if everyone could bend a little.
And that's an easy place to bend.
