    Instead of offering the options `IGNORE` and `LOG_ERROR`, we should probably just always
log a warning (if `REDUCE_ON_FULL_COMPACTION_ONLY` is not set) and let users disable it in
the log4j config, rather than in code.
    The `REDUCE_ON_FULL_COMPACTION_ONLY` should be treated as a distinct boolean value which
can be set to `true` or `false` as a normal iterator option (similar to `Filter`'s `negate`
option), with a default value of `false` to preserve existing behavior.
    That would also minimize API changes, especially for 1.6.x and 1.7.x. While this isn't
technically public API, it'd still be good to minimize API impact on users using those versions.
