In some ways it does, but then every callback has to start with a check 'is
this an actual only child?'
And most likely we forget that check in a dozen places, because it is so
unlikely to find these actual only children in test scenarios.
So the result will probably be that Subversion fails for end users...
because almost none of our functions accept these actual only children. (I
think only read_info with a conflict argument and the tree conflict
