Well, it _might_ be better.  It depends on what you're trying to achieve.

For instance, DNAMEs are sometimes introduced in order to move
operators.  If the losing operator is hostile, then actually having
the old service data being served authoritatively could be worse than

It certainly must if the issue isn't fixed -- it'll hit the expire
time.  You seem to be suggesting that the slave server needs to be
upgraded in some way before the new (unknown) RR can be accepted on
that slave.  The decision about that may not be under the control of
the zone administrator, becuase the slave name server might be under
the control of someone else.

Best regards,
