Reserved general punctuation

My naïve assumption is that anything unassigned has the potential to become assigned so we need to have a state in which the code point is not allowed for current use but could be permitted at a later time. Do we have the semantics to accommodate that? V

One view could be that as the block 2065..2069 is defined as  
Other_Default_Ignorable_Code_Point, why would it not be DISALLOWED?  
Because when the codepoint is assigned, this might change?

Another view that all unassigned codepoints (as defined by not being  
defined in UnicodeData.txt) are UNASSIGNED.

What do you all on this list want? Today we are implementing the first.
