It still looks like to me that you are recording two distinct types of parent using the same type of link. You're now just expanding the definition of parent so they look to be the same. Actually it might be alright if you have an extra merge commit object. ie, make a complete merge of the new tips, then make a second merge that merges the two heads. It's still a little bit of a research topic to look at that mess and figure out which type of relationship each parent actually is, but if you really want to decide that is that and done is done then I guess we'll all just have to live with it or fork.
