That's not an issue when it comes to acquiring immortality though. I mean, if you lost all knowledge of algebra, would you say that means you "died"?

Did you not read that section at all? If you lose all knowledge of powerful spellcasting, a) you lose your ability to continue to be immortal after this iteration, b) you lose your ability to defend yourself against enemies who haven't lost their ability to cast interdicted spells. The second one is really important when the process for immortality is one that inherently makes a lot of enemies! He specifically mentioned that dark wizards that tried use that technique to come back were easily defeated afterward.

Could that explain why Hat&Cloak seems to be a clever manipulator who works in utmost secrecy? (They really are weak, and survive only by hiding in the shadows.) We never see them indicated as using anything more complex than an Obliviate or disguise spell, AFAIK, which any reasonably competent adult wizard would be able to pull off.

That's irrelevant when you're considering whether or not to use the horcrux at all and the alternative is being dead.

If you're on your deathbed, sure. But Horcruxing is not costless. If you have a significant projected lifespan left, and you want ACTUAL immortality, your odds are probably better NOT doing a risky dark ritual that also encourages people to come and kill you.

This seems a big part of why I don't think Baba Yaga is still alive. The best in-story reason I can think of to consider the theory at all lies in the idea that (if Horcruxes are easier to make than I thought) some Dark figure of legend should still be alive. This argument seems weak if the spell doesn't give you much advantage. Also, Quirrell's claim here fits what we know about the Interdict. (I guess the question is whether the Horcrux spell falls under the Interdict!)

Chapter 39:

Voldemort stole the book from which he gleaned his secret; it was not there when I went to look for it.

Yes, but Dumbledore probably can't create an Horcrux. The Defense Professor claims the known description is wrong, which could make the theft a piece of misdirection. This is another possible way around the Interdict; publish a fake version of the spell which hints at the truth.
