Thus, you'd best make changes before or after the transfer has concluded, successful or not. I'll look around and post if I find any "rule" regarding this. Probably an RFC or something...
Now that you mention it, I don't know what's the rule either. But I do know registrars won't allow anything to happen to a domain name when a transfer request has started, be it renewing the name or even change DNS.
