genetically, there is no difference from using a real male, or a reversed female(except ofcourse the progeny will be all female). no messing up of genes or anything, you can freely breed with feminized seeds.
however, I think the confusion comes from people who don't distinguish between hermi's and feminizing.
children will be similar to their parents(ofcourse not exactly the same, and it depends how stable/inbred the parents are, but still, you'll see traits from the parents back in the children). so breeding with hermis is a bad idea, since the children will be more likely to be hermis too.
however, when feminzing with chemicals, you're messing with the hormones. the plant may look like a hermi, but it has no increased genetic tendency to hermi(ofcourse to be sure pf no hermis it should still be tested for hermitendencies before using it to feminize, but the process of feminizing itself has no influence on genes, just hormones).
there is the thing with inbreeding depression(think of medieval aristocratic families in humans: keep getting children within your own family, and you'll start to see negative mutations that were already there, but were hidden, that come out when inbreeding), but if you don't want inbreeding, you can just cross 2 unrelated females.
crossing a plant to itself(selfing) which feminizing makes possible is a more extreme form of inbreeding as brother-sister inbreeding, so you get quicker results when breeding, buit also hit inbreeding depression faster. your choice how much inbreeding you want to do, it's a balance between an unstable strain/line and inbreeding depression.
however if you reverse a female plant, then pollinate one of her sisters with the feminized pollen, it's exactly the same as using a brother for inbreeding. but the children will still be all female.
so feminizing is a nice tool, and you have to decide yourself wether it's the right tool for the goal you want to chieve with it.
personally I think some people in the weedworld are a litttle too afraid of inbreeding depression. sure, it's bad, but unstable genetics that don't breed true at all are bad too.
