I'm fairly sure that we don't implement the protocol exactly as specified,
although I don't remember now what the problem was.  There was some reason
why we weren't providing HDR and OVER, though.  Note the comment:

It needs a careful review, particularly in edge cases and error codes,
before we advertise it as HDR or OVER.

That's the right approach in the long run, with the appropriate responses

CAPABILITIES should only list documented extensions.  XHDR and XOVER
aren't documented extensions, just legacy commands.  But yes, they should
all be listed in help.
