• bug fix
• BC break? no

use App\QueryCostsBootstrapped;

use App\QueryCostSet;

I think that this is better:

use App\QueryCostP;
use App\QueryCostR;
use App\QueryCostT;
use App\QueryCostsBootstrapped;
use App\QueryCostsXyz;

than this:

use App\QueryCostP;
use App\QueryCostR;
use App\QueryCostsBootstrapped;
use App\QueryCostsXyz;
use App\QueryCostT;
