Not really, remember that the planner is trying to balance media usage
over the full dumpcycle, not just today. And for a specific example,
suppose your incrementals, obviously critically required, take up
90% of the available tape capacity. Further, the DLE's it would like
to to do as full dumps will each take > 10%. They can't be done. But
if a small DLE is promoted today, there may be more room available on
the a future dump because that DLE doesn't require its full dump.
