Why is there no --p-cores in the qiime dada2 command?

qiime cutadapt can set the number of cores used, like

qiime cutadapt demux-paired
--i-seqs Multi.qza
--m-forward-barcodes-file metadata.tsv
--m-forward-barcodes-column barcode
--p-error-rate 0.3
--p-cores 24
--o-per-sample-sequences Demulti.qza
--o-untrimmed-sequences Untrimmed.qza

Why qiime dada2 doesn't have this feature. I want to make the dada2 process as fast as possible.

In Dada2, one can use
to achieve similar results.
