(This is completely untested.)
Why can't you build your 10.in-addr.arpa zone as follows:
10.in-addr.arpa. IN SOA ...
1.10.in-addr.arpa. IN NS <bla>
2.10.in-addr.arpa. IN NS <blabla>
220.127.116.11.in-addr.arpa. IN PTR host-10-3-4-5.local.
(Glue records as appropriate.)
In other words, rather than creating each class A as a separate zone,
why not put all of 10/8 in one zone and delegate just what you need /
Granted if you wanted to you could split up the zones that stay local so
that you don't have too many lines in the one big zone.
Just thinking out loud.

This is untested, but I don't think there's any reason why what I'm
suggesting wont work. (I may need help from others with syntax.)
You /might/ want to slave the zones off of the delegated servers to
offer a central place to get to all of the zones.
Grant. . . .
