We'd certainly like to test this implementation, but we need someone
who's familiar with it enough to run it and fix any issues found.

That's the idea here. We want to test whether we missed anything, what's
the most reasonable behavior in odd corner cases etc.

I would be cautious with using "secure" and "3315" in the same sentence. :)

Yes, there are. First, there's secure DHCPv6 draft that's being
currently actively worked on draft-ietf-dhc-sedhcpv6-12 [1]. It's a
significant step forward as compared to what 3315 offered.

Second, there's RFC3315bis work [2] in progress that hopes to clean up,
clarify and fix lots of issues in DHCPv6. The current draft is
dhc-rfc3315bis-04. There's a whole separate mailing list and issue
tracker [3] dedicated to it. Authors are planning to publish -05 version
in the next couple days. If you're interested in what has changed, we
maintain a changelog (see Appendix A). It may not be exhaustive, though.

One of the changes in 3315bis is the Delayed Authentication mechanism
being deprecated. The mechanism was underspecified, difficult to deploy,
had significant operational burden and its actual deployment in
production networks was extremely limited at best. As there's a new
alternative (sedhcpv6), we decided to get rid of the delayed auth.

Both of those drafts are hoping to go through WGLC (working group last
call) in the next couple months. Feel free to review them and post your
comments here.
