Yea! I am under the impression that still missing functionality is nsec3?
The trace below reveals another problem, but that's fixed now.
NSEC3 remains to be done.
I'm still in a quandary about stripping DNSSEC information from upstream
answers when the question doesn't set the DO bit. Strictly that's a MUST
in the RFC, but my judgement is doing it is more likely to cause
problems ('cos it's difficult to do robustly),
I've just had doubts about trust anchors, see separate mail.
Is the local-to-dnsmasq domain signable?
No.
Cheers,
Simon.

Yay, seems to work:

Dunno why it starts out insecure (?), but seems to get to the right
place.
