Robot blocking microformat

How about I rename my robot-blocking profile as a microformat and see if that gets any discussion going?

And while we’re at it, can someone please explain for the record why microformats aren’t encouraged to specify HTML profiles (think namespaces for metadata) to formalize the idea that User agents may… perform some activity based on known conventions for that profile? Because a profile only applies to the document’s HEAD element is not a valid argument.
