Hello!, did anybody test this further?. I have the same situation, we're some hostnames can be resolved (whatever was served by firewall A, but any lease served by firewall B fails to resolve).
I understand static mapping would "solve" this, but it not always desired (highly dynamic environments)
As DNS By itself is capable of providing ultimate redundancy -> the whole internet relies on that principle ;) , couldn't it make sense to just use the DNS function which is intended for this case? I talk about using DNS-Replication. so "Opnsense device 2" just replicates from "Opnsense device 1" and in case of failure "Opnsense device 2" continues to work, only new DNS-Records will not be created automatically, till you exchange the primary and secondary role.
