Perhaps my build is messed up, but I just updated along netbsd-9 and netbsd-10 and rebuilt.
On -10, I got new shlib versions for bind and unbound libs. That's ok because 10 is not yet released. On -9, I see in my destdir: -r--r--r-- 1 gdt wheel 143494 Mar 26 12:59 /usr/obj/gdt-9/destdir/amd64/usr/lib/libbind9.a lrwxr-xr-x 1 gdt wheel 16 Mar 26 13:00 /usr/obj/gdt-9/destdir/amd64/usr/lib/libbind9.so -> libbind9.so.21.0 lrwxr-xr-x 1 gdt wheel 16 Jan 30 12:49 /usr/obj/gdt-9/destdir/amd64/usr/lib/libbind9.so.13 -> libbind9.so.13.0 -r--r--r-- 1 gdt wheel 74720 Jan 30 12:49 /usr/obj/gdt-9/destdir/amd64/usr/lib/libbind9.so.13.0 lrwxr-xr-x 1 gdt wheel 16 Mar 26 13:00 /usr/obj/gdt-9/destdir/amd64/usr/lib/libbind9.so.21 -> libbind9.so.21.0 -r--r--r-- 1 gdt wheel 95744 Mar 26 12:59 /usr/obj/gdt-9/destdir/amd64/usr/lib/libbind9.so.21.0 -r--r--r-- 1 gdt wheel 147542 Mar 26 12:59 /usr/obj/gdt-9/destdir/amd64/usr/lib/libbind9_p.a which makes we think we had a pullup with an ABI change. I think this is tickets 1804, 1805. Or, do we claim that these libs are private to bind, and thus this is not an ABI change? (I have not tried to boot this system - I'm at the stage where the build failed because there are old files in destdir. That's not an error in current, but it's irregular in 9.)
