I never stated Senju DNA was necessary, I did state Hashirama's DNA was necessary; Hashirama, not the entire Senju clan is held in high regards for possessing an outstanding life force. The Senju clan has nothing to do with it.

I mucked up in regards to the association with being a master medical ninjtsu user; standalone being one would well, mean certain death if this technique were to be used in a near-death state and then some. I suppose that while it may be used by virtually any master medical ninjutsu user, there'd really be very little benefit following the recovery-chakra exhaustion tradeoff.

Naturally Hashirama didn't need Sage Mode for it, he already possessed the godlike vitality to use it with minimal penalties. Madara needed it even with Hashirama's DNA implanted in order to, I suppose enhance that implanted DNA's vitality a boosting property to achieve a similar level of regeneration as Hashirama (because Madara's vitality clearly inferior to Hashirama's without his DNA implanted) without disadvantaging himself.

I suppose that you could claim it after all, although unless you can somehow attain a godlike life force, which would be incredibly difficult, controversial to boot without Hashirama's DNA implanted (among other variables), then it'd barely serve as an advantage, if not an outstanding disadvantage.

Nerfing it's one approach, though personally I believe a separate section should be made on the page detailing the impact it'd have were somebody with inadequate requirements, such as a master medical ninjutsu user with inferior-to-Hashirama life force to use it. Something along the lines of using up a tremendous amount of chakra, even for regenerating an arm from scratch would do. It's barely battle-suited anymore, but oh well.
