Control panel pages that don't require any fancy widgets are really easy
thx to formlib. If you look at my examples in plone.app.controlpanel,
you will notice that they mostly consist of lots of boilerplate code one
can copy'n'paste ;)

I'm mostly concerned about search engine crawlers revisiting already
indexed sites. Not sure how much traffic those generate these days,
though. Other than that the usual attacks websites have to endure come
to my mind, like bots looking for insecure PHP apps on your domain (like
awstats, phpmyadmin, ...). But probably you should filter those out in
Apache or Squid in front of Plone anyways.
I don't think a config option is a priority, but rather a nice-to-have

OK, call it YAGNI for now.
