I took @joewitt's comment to mean keeping the combined bundle and
documenting that attributes are not stable and could change with version
upgrades, which will apply to both bundles if we break them out. At some point
the [MetaData
Extractor](http://search.maven.org/#search|gav|1|g%3A%22com.drewnoakes%22%20AND%20a%3A%22metadata-extractor%22)
will need to be updated no matter what, the original 2.7.2 dependency is from
Jan, 2015.
