Here is some more explanation :

It really is not odd when you come to work with it in real life. This rules

position, and how different configure requests will be handled based on the
Another reason why that should be mandated is that if user specifyes

command line parameter - it expects it to be honored, and the only way for
to be honored is to mandate specified behaviour to Window Manager.
Of course Window Manager is free to disregard configure request entirely
or in parts, and this specification by no means interfer with this ability.
What is mandated is HOW request should be handled if IT IS honored.

Unfortunately this part of ICCCM is what is most widely misunderstood,
