limit-req and greedy UAs

Has anyone considered the problem of legitimate UAs which request a
series of files which don't necessarily exist when they access your
site?  Requests for files like robots.txt, sitemap.xml,
crossdomain.xml, apple-touch-icon.png, etc could quickly cause the UA
to exceed the limit-req burst value.  What is the right way to deal
with this?
