Thanks for the followup information, and sorry for the jargon I used ("MIR": Main Inclusion Request).
It means that in order to (re)enable this support in bind 9.16.x, we need to move the libmaxminddb package from universe to main, since bind9 is a package in main. That process is ongoing in the other bug I linked (https://bugs.launchpad.net/ubuntu/+source/libmaxminddb/+bug/1861101) and once that is done, this bug you reported here will also be fixed.
