If this is actually the prevailing opinion then maybe it really is 
important.  But I think of this kind of stored order the same way I 
think of the stored order in a directory on the filesystem, or the order 
of the items in a Python dictionary.  There is a default order, but no 
one uses it.  It is unreliable, unpredictable, and no one expects the 
order to be preserved.  Order preservation is accidental.

In Zope 3 it will be possible to configure this choice.  You'll be able 
to say that when the user asks to create a "Folder", they really get an 
OrderedFolder object.  In Zope 2 there is no clean way to make this 
decision.

It seems to me that a little patience would be prudent, folks. :-)
