Yes, the fact that HTML5 makes unregistered values invalid is a problem 
that probably should be tracked separately (see related issue 
<http://www.w3.org/html/wg/tracker/issues/102>).

I'm not convinced that insisting on what HTML4 said is constructive 
though. It's pretty clear that there is a de facto global namespace of 
name values, and HTML5 needs to say something about it.

"Robots" is mentioned as "proposed" -- not "approved" -- in 
<http://wiki.whatwg.org/wiki/MetaExtensions>.

Note the current requirements listed over there:

"For the "Status" section to be changed to "Accepted", the proposed 
keyword must be defined by a W3C specification in the Candidate 
Recommendation or Recommendation state. If it fails to go through this 
process, it is "Unendorsed"."

So I would consider this as proof that the registry doesn't really work, 
or that the registration requirements are too high (is anybody going to 
write a W3C Rec defining the "robots"?) -- again, this is related to 
<http://www.w3.org/html/wg/tracker/issues/102>.

Best regards, Julian
