We don't use WiredTiger block compression for secondary indexes on non-clustered collections because we already use prefix compression and the stored RecordIds are pretty compact.
Clustered collections have larger RecordIds which take up more space, but may compress better.
We should evaluate using block compression for secondary indexes on clustered collections to reduce storage size.
