Hi Bernd.

Why?

Not productively.  We could have "if the PersistentReference doesn't  
have the 3.9 stuff then just refuse to do a ConflictError" but then  
that's no different that the keyreference 3.4 behavior.  Heh,  
actually, that's effectively the behavior we probably have now for  
keyreference 3.5dev running against ZODB 3.8, since errors in the  
conflict resolution will simply cause the resolution to fail, and the  
3.5dev changes would generate AttributeErrors against ZODB 3.8 during  
conflict resolution.

So...it would be a bit of a lie to claim to be compatible with 3.8.   
The changes are useless without the 3.9 changes.  But the code  
*should* technically work with the same restrictions we have now.   
That said, I don't really want to support the changes against 3.8.

...I could move the releases to our ZC download location, rather than  
the zope.org one, if folks want...

What's the problem?  I'm happy to help, especially if it doesn't take  
too much time, and you can wait a day or two.
