I understand what you're saying but just because it's classified as a clan ability doesn't mean that others had it. Hashirama's Wood Release is unique only to him and he is the only known user of it yet his usage of it has earned the whole clan the name "Senju of the Forest" despite only having one user. Hashirama's WR is unique to him like Kushina and Karin's ADS is unique to them since they're the only known users. So if you're going to make some hypothetical scenario in which the Senju and Uzumaki learned everything they potentially could then you'd have to give all of the Senju Wood Release as well which would outweigh the Adamantine Sealing Chains.
