Your viewpoint is right in general, but may not in this special case in which
the centralized deployment of VGRS solution is based on gTLD servers.
gTLD server will remain under centralized control of ICANN forever.
If ICANN order "turn off the 8bit-query support " after 2 years,
VGRS should follow. From then on, end users should install
the plugins manually. I can't see any big problem here...
Surely 8-bit support is a current characteristic of DNS? - certainly BIND
supports the transit of most ASCII 8-bit characters and this is good
functionality.
