Okay to merge included columns on otherwise identical indexes?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I have two indexes that index the same field on the same table. The only difference between them is the included columns.
There's no reason I shouldn't combine the included columns and just have one index, right?

Yes, you should merge these indexes and only keep one, as long as you verify that:
Neither of them are marked as
UNIQUE(in which case, preserve that one)Neither of them have a filter condition
Neither of them are expressly referenced in an index hint
