My understanding is consistent with Alain's, there's no way to force a tombstone-only compaction, your only option is major compaction. If you're using size tiered, that comes with its own drawbacks.
I wonder if there's a technical limitation that prevents introducing a shadowed data cleanup style operation (overwritten data, including deletes, plus tombstones past their gc grace period); or maybe even couple it directly with cleanup since most of the work (rewriting old SSTables) would be identical. I can't think of something off the top of my head, but it would be so useful that it seems like there's got to be something I'm missing.
