This is an interesting suggestion, but I don't think I'm going to make the change.
If someone doesn't want Feedwhip crawling their site, then I need to respect that. The problem is that even though Feedwhip is what I think of as a "benign" crawler, most people just block *all* web crawlers.
The only thing I can suggest is to talk to the owners of the websites you're interested in and see if they'll add an exception for Feedwhip. It's easy to do, and that'll give you a pretty direct answer as to whether they want Feedwhip looking at their website.
