Yes, I have been seeing the same thing. That is one thing that has
delayed deployment of v6 in our office LANs as many have Macs.

In our case we have a maintenance window with the remote network on the
phone, change the resource, test connectivity, and if it works, call it
a day and move on to the next one. And v4 connectivity won't stop
working just because v6 is available but in our first migration targets,
I expect nearly all the traffic to migrate to v6 pretty much instantly.

Yes, absolutely agreed. That is exactly why we have delayed doing this
until we have all of our internal T-s crossed and I-s dotted. We needed
to announce our network to two different external transit peers, needed
to upgrade code on load balancers and other internal gear, deploy
separate instances of named, etc. That process is nearing completion.
Only once we are fairly convinced we have everything as "correct" as we
can get it, will we register the v6 name server in whois and roll it out
to a partner.
