Not saying you are wrong here, but have you an RFC reference 
to this effect?  We previously held this belief from our prior 
practice, but cannot find a clear prohibition of such.  As 
such our DNS zonefile management code does not enforce such a 
limitation presently

Considering the issue from the other side, there is nothing 
that requires simplicity if implementation of a client that 
says it can accept only a single PTR, rather than an array of 
replies and then walking the reverses
