Detaching twice

[Ir00man]

Do you think that detach() method should detach all related models OR only those are attached?
I mean if call something like this: Post::find(495)->tags()->detach(); twice deleted_at column will be updated 2 times.
Can we leave records untouched in pivot table when they are already deleted (deleted_at column != null)?

Actually my problem can be solved by using Post::find(495)->tags()->sync([]);
This way deleted_at column will not be updated if it's not empty.
But still do you think that detach() method should respect already deleted records and keep them as is?

I think this is good idea.
