In the case of Six Paths Senjutsu advanced transformations, which are classified as Sage Arts, I suppose it's because it's not "genetic" on any level. Six Paths Sage Mode grants knowledge, not blood ability. That's the only way I can really make sense of it. The same is true for Madara's Ranton, which is a Sage Art and achieved through the Six Paths Ten Tails Coffin Seal, which is comparable to Naruto's Sage Mode.

They probably corrected Sage Art: Boil Release to just Boil Release because Naruto was using the Tailed Beast's chakra, which has special properties, and thus makes it a Kekkei Genkai, not Senjutsu.

Did I crack the code? Kind of?
