At its core, this is about putting public property (ie,
an
existing international standard) in proprietary
hands... like having a troll
trying to assert copyright on the flags of the world.
The fact that there are exceptions to reservation of the standard (.com, .uk) does not negate the validity of the standard going forward. Going after it will simply diminish trust in ICANN even below its current awful levels, and at some point this diminishing trust will affect DNS stability.
As for the GACophobia...
f
ine. As Olivier suggests, punt it to the ccNSO first and see what they think. That's critical feedback to this issue.
