Toby, At some point, yes the "missing" space is recovered. But that does not mean the deletes will be found immediately upon 2.0 upgrade.
2.0 adds statistical data to each newly generated .sst table file so that it "knows" where delete entries are hidden. The statistical data drives the aggressive delete removal. Normal compaction grooming will find the deletes in 1.4 generated files over time. Time here could be measured in months. It all depends upon how fast your data is filling "levels".
