If you mean v_pk_minimum3_f16 and v_pk_maximum3_f16, then FeatureMinimum3Maximum3PKF16 already exists.

New IEEEMinimumMaximumInsts will include v_pk_minimum_f16 and v_pk_maximum_f16.

You want to have just v2f16 legal when only FeatureMinimum3Maximum3PKF16 exists because of MinimumMaximumByMinimum3Maximum3VOP3P? That would not be NFC so I do not want to put it here.
