I truely have learnt something I didn't know before. But both registrars have to agree the transfer, not just one. And since the rule doesn't give any reason for giving or not giving their approval, it's at their discretion. But if the transfer was going in the other direction, I wonder if GoDaddy would be so willing to undo their lock. Because they seem paranoid about it. I repeat. What the rules say is that BOTH REGISTRARS HAVE TO APPROVE THE TRANSFER. If either registrar doesn't give their approval, the transfer would not proceed.
Your example seems to me to be a very narrow example. We now know that at least NameCheap will give their approval. So what are the other examples where you see this could be beneficial?
I have quoted you the also narrow example where GoDaddy (or another registrar), might not give their approval. I don't see why you have to use your lecturing tone with me. This is a discussion.
