The L-root operator (ICANN) will stop serving from the old IPv6 address.
It's well past time we stopped treating resolver operators like children.

I'm not clear on what you are asking.  What is a "onetime" resolver?

A resolver that only uses L-root once? something else? (and given the way
DNS operates a real resolver could still only use L-root once as it finds
a better RTT to another root server operator.

That depends what people are monitoring for, and how.
