"it is signed" does not imply "an off-the-shelf client will do local
DNSSEC validation and fail on DNS64 replies"...  but out of curiousity:
is there anyone defaulting to "validation on" in their stub resolvers?

This is correct, and well understood.  The question is "is this relevant"?

And if this is relevant, will it excert enough pressure on major sites
like slack.com to add an IPv6 endpoint?  It's 2026, after all... no
valid excuses anymore.
