It's not a ludicrous complaint, however it's unlikely to succeed.
I'm sure there are people that would prefer not to send this information and most are probably unaware that it is sent. Therefore, I think it would be reasonable to offer the option not to send this information. This could easily be achieved by processing search requests using the POST method instead of GET.
I know that webmasters won't like this idea, but that's life.
