Not really.

In either case the software that signs zones has to be updated.

If the output is in text format, the generic text format of RFC3597 section 5
may be used if the serving software for the master server has not been updated.

The software for secondary servers does not need to be updated in any case,
assuming it implements RFC3597 ( that is it can handle unknown types ),
which is of course the case for all mainstream implementations.
