Hermies bad?

From what I've read, generally hermies are a bad thing. But "Sometimes a female plant contains male flowers, its rare but it happens. The male flowers on a female plant contain the same chromosomes as the female plant itself (X-X). This means that the Female plant can fertilise itself and can grow seeds that can only contain Female Chromosomes and thus grow female plants." So if a hermie is taken away from your main grow as soon as it's showing its sexes, and allowed to go to seed, wouldn't you most likely have a supply of feminized seeds?

Hermies are bad and they are caused by stressful situations. Hermies can produce feminized seeds but those seeds may be even more sensitive to stress and might produce hermies also. If you ask me it's not a good thing and I would just try to keep my plants in the best conditions possible, stress free and hope they produce lovely ladies.
