No, according to the original design philosophy, this is *not* an
implementation detail. It accurately reflects the theoretical
design. Read on.

See, there's the difference. I don't think Subversion was ever
designed with the idea of allowing node history to "join". Historical
forking, yes, but no joining. I gather from your basic imagination of
a node's history that this is something you think we *should* support,
though?
