Well, these stealth- based techniques are just that: they are techniques. Anyone can make a technique for the application of chakra, but those techniques are never stated to involve any special genetic component. Kekkei genkai are different in that they, by necessity, require the right genes. Utilizing chakra in a normal way is different from the application of a kekkei genkai. Also, while Hagoromo didn't spread his teachings to be weaponized, there can be no doubt that they have enormous potential for violence.

I don't feel that it is a more radical assumption. Kekkei genkai are rare, and we've only scratched the surface of how many people Kaguaya's bloodlines have spread to.

There's never been any evidence that just having a strong affinity for a basic nature could help create an advanced nature in one's child. The only people that have them (as far as we know) come from families that have proven to have those genes in the past. Until we have evidence of a spontaneously created kekkei genkai, I can't believe that.
