FWIW, the intent in this Section wasn't to change that.  The text was 
meant that, when discussing how "scope" affects other properties of IPv6 
addresses, for all practical purposes ULAs have limited scope.

This text predates draft-gont-6man-ipv6-ula-scope which effectively does 
try to formally update the scope of ULAs.

P.S.: I will update the text before the cut-off.

Thanks,
