I resolved the same issue by writing some very small software to generate the
view statements, and in some cases the zone database, from a source that
didn't feature the redundant information.

That was actually fairly trivial to do, in my experience, especially with the
'$INCLUDE' statement to allow common zone data to be defined only once.

Not that there is anything wrong with the other method; just another approach.
