no not ironic, while it's not adivsed to breed hermie genetic over many gerneration growing them pose no issue at all most of the time
first it all depend what kind of hermie your dealing with.
strong hermie showing lot of balls cluster on nodes or inside the tops, i personnally never encountered such hermie
strain that are prone to hermie and that only a few pheno per batch will show few balls bottom of canopy with lite environnemental stress first few weeks of flowering stretch.
in this case just keep a watchfull eyes and pluck the balls.
i have grown countless of lite hermie without getting any seeds in the end.
