The fix was already high in the priority list anyway, but I'll try to make sure we don't postpone it more. Had I realized sooner, I would have made it so we'd release it earlier.
According to the package definitions, we even overwrite it each time we update the xcp-ng-release-config package. I'm surprised that we haven't had more support requests.
I'll see if we can release a quick fix that just leaves the file alone until we apply the change that will move the remote configuration to its own file.
