I'd be apt to not further restrict the set of identifiers an OFS content
object can begin with as long as we can get away with it.  If a user
happens to enter one that starts with a "view character", I suspect a
developer could just choose to not allow this in at the application level
if he cared (e.g. if he were using Five).  It might be reasonable to add
this to CMF instead of Zope, but  IMO, it's a bad idea to put theis
particular restriction in either place, as it will almost certainly break
somebody.
