Well we do know is that Uzumaki can seal "Exceptionally powerful beasts" or even enemies. Possibly as clan they possesses remarkable summons. So the most exceptional ones could seal it for future use while the weaker members could "summon" the vanquished ones. This would make them different from Uchiha's as Uchiha cannot "share" their power. Also coming to whole chain thing, there is a good chance most members possessed it though not at level of kushina or mito. There is no prerequisite to the chains other than strong chakra and practice. They could easily train their hiden to members of the clan like the current Ino-Shika-Cho or even Aburame clan. And Finally in Uzumaki's defense, there village was destroyed by 3 villages which decimated huge nubers on both sides with several members of Uzumaki surviving the onslaught Where as not a single true Uchiha is left today other than Sasuke.
