So exactly what could happen if we use a bidirectional relationship without
setting one way read-only and set both sides of the relationship explicitly?
I believe I'm just doing that and *never* experienced any problems. Beside
that, I feel it quite an overhead doing all this manually, so I'd like to
know about both the drawbacks, the dangers, and why that's all unavoidable
doing so, or why it cannot happen automatically in the background..

thanks for the explanation in advance,
