Henrik, All,
I am still reading my way through this large discussion. Here is are two 
points I already can make:

If we want to allow for tolerance here, we would have to declare it to be 
mandatory, otherwise clients could not rely on it and it would be useless.
Tolerance can be good to support old non-conforming client or future uses.
Georg's proposal is consistent in this regard.

As the problem we are trying to solve actually comes only from recurrent 
objects from tasks and events. One idea I have is: What about we make a 
change to the format that only newly written tasks and events that include 
recurrence MAY use the new format?
Newly written means a new or changed event. This way new clients 
would stay mostly compatible with already existing ones.
