That may be true. I do think however that an OrderedObjectManager (which is
what the discussion is about, right) is something that would be very useful
for almost every Zope developer, and therefore really should be in the Zope
core.

An ordered folder in Zope core wouldn't be a problem either.

Having the standard folder be ordered could be practical, but it's more
work, since you want to be able to change the ordering on a folder so it is
either ordered by name, date or order. It's possible, but I agree that it's
not nessecary.
