Sure, but the original question was about clan breeding protocols and the iron womb technology for "other" purposes.
They're useful tools, but not in a large scale manner for the Magistracy. Large scale use would seem to indicate some of servitor or warrior caste, which goes against the Magistracy's ethos of individual freedom.
If you got around the whole designer child issue, then sure, I could see some parents going for a kid that's potentially faster and stronger and what not, but that's again a small scale issue,since they want 1 perfect kid, and not 300 in a sibko. So you wouldn't need mass amounts of Iron Wombs, beyond what you might need for pregnancy issues.
Very good math point. Off-hand each Iron Womb would be good for 1 child per year, so a planetary population of 1 billion growing at .5% of its population annually, if using just Iron Wombs would require 5 million Iron Wombs (with that number also needing to grow at .5% annually). I estimate the Clans as a whole only have ~400,000 to 800,000 Iron Wombs.
(Clans overall have 115,000 Warriors, average age is 45. Assuming 30 years between testing out and dying, means about 4,000 IW were needed to produce them. If each sibko only graduates 1 Warrior, and since each sibko is over 100 people, that means 100 IW were needed to produce that Warrior, so that is 400,000 needed to produce the steady stream of Warriors. If more than 1 Warrior is produced, then divide that 400,000 by the average number of Warriors produced per sibko. If more than 100 kids is the average per sibko, take that average and multiply that by 4,000. If the Iron Wombs are not 100% effective, then take the number of Iron Wombs and divide it by the % of children that come out.)
Rough math: (Number of Clan Warriors * number of kids in a sibko) / (average number of years each Warrior is alive * number of Warriors produced in a sibko * Iron Womb success rate)
So yeah. Like any medical technology, the iron wombs would be helpful, as would potentially the genetic engineering information, but not on a scale where the Magistracy would be producing legions of X.
Since this is the Magistracy, it would technically be legions of XX ;D
