We are about half way through a release cycle. I’m not sure if we
would get your patch into the next release or not. We would definitely
put it into our bug system so it wouldn’t get lost.

yes, my patch should do that.
Similarly for NA addresses as well
there is also a change to the scoring algorithm to choose leases
from different servers (if you actually have two or more dhcp servers
to choose from). The new scoring prefers more bindings over more
addresses. So a lease with an IA_NA and IA_PD with one address (prefix)
each is preferred over a lease with an IA_NA with two addresses.
