Your declaration of what I take into account is false.

If you put XXX into your calendar:
        don't tweak it if it will break you or your CUAs.
        If you do not want other to be able tweak XXX, put in a VCAR to 
stop them.

If you did not put XXX into your calendar
     don't tweak it if you do not know what it does.
     If it has a decreed VCAR, you can't tweak it anyway.
     If you do not like it, and you have permission, delete it.

This is NO different than any other component. If you tweak a VEVENT
and add a RRULE, and your other CUA can not handle RRULE's, it is not
the protocols fault and has no moral (bad) implications.
