Yes its not specified but The Gotei 13 have not ever been allied with the Quincy from the information we have and there is no information that allows us to assume otherwise so its a huge mistake to assume the gotei 13 know anything about of the techniques or capabilities of the Quincy other then whats basically shown and the small amount of info Mayuri garnered and kept to himself. They didnt know virtually anything about th Quincy this past arc. Also Ryuken is the one who heard of Still Silver, Uryu didnt even know what it was, for if he had he would have had an actual plan to defeat Yhwach instead of coming in there with nothing and then deciding blowing everything up would work. Looking at the panel and assuming Uryu (due to his presence) being involved in the voice over of the significance of the Still Silver is misleading. Ryuken is the one that gave him the arrowhead, the one the extracted the silver from Katagiri, the one that knew it was there and why it would be helpful. Uryu is simply remembering what he was told by his father (off panel most likely). Thus my point Soken had one passing point there but all this information and action in the present was the doing of Ryuken. Soken may have presented the concept but all the work was done by another. You have multiple occurrences of Ryuken and one voice over noting Soken contribution, apparently telling Ryuken about it. As I said from what we know Soken lived a normal human life and just because of Bazz-B and Hashwalths age (which is unexplained) it doesnt mean anyone else lived as long. There is nothing to state Soken was anything more then a typical Quincy of the present day that in relation to other quincy saw the changes in technique and the the aggressive philosophy counter to his cooperative one and distanced himself from them. The quincy have existed since 1,000 yrs ago at their primary defeat well into the present time thus there is no telling a what point Soken was involved with them, but we have no information stating it was centuries ago so we have to go with present time.
