The kernel is applying the RA managed/otherconf flags silently and
forgets to send ifinfo notify to inform about their change when the
router provides a zero reachable_time and retrans_timer as dnsmasq
and many routers send it, which just means unspecified by this router
and the host should continue using whatever value it is already using.
Userspace may monitor the ifinfo notifications to activate dhcpv6.

Applied, but more ideally this function should emit only a single
NEWLINK message rather than potentially 3.

Yes, you're right of course.

I've attached a follow-up patch doing this. Please let me know if you
need it in a separate mail.
