My final question is: can I expect a patch adding such command-line option to be accepted?
No. I agree with you that it would be nice to make it easier to create robust multi-user setups, but the way to do that is not to provide an option to bypass the security check. The check is here because it's currently not possible to make multiple users share a wineprefix reliably; playing with permissions is certainly not enough, sooner or later you'll get a corrupted registry.
What needs to be done is to fix the code so that the multiple servers case is detected and handled correctly. Once this is done the check can be removed.
