Invisibility cloaks in canon are supposed to be made from demiguise hairs or enchanted, and not usually made out of thestral components even though thestrals are invisible. The true Cloak of Invisibility may be using the thestral blood for permanence as well. Most cloaks of invisibility fade and weaken with time until they are useless; until Harry discovered a secret use, the primary difference of Harry’s cloak was it’s ability to last for so long.
In canon, people are extremely prejudiced and superstitious against thestrals. They also share the same XXXX classification as trolls, according to Quirrel “the third most perfect killing machine in all of Nature.” This means they’re probably illegal to handle or acquire without ministry supervision. I would guess that most people don’t have the means or desire to experiment with thestral blood.
Lastly, Felix Felicis is a super finicky potion. It is toxic in large quantities, difficult to brew, and dangerous to get wrong. The inclusion of thestral blood made an ordinary (well, 5th year) beauty potion extremely dangerous; people may not want to risk making it even more dangerous.
Although, all of these are just speculation so take with a grain of salt. But it would explain how thestral ingredients grant permanence, but aren’t used commonly.

IIRC, both canon & MoR flat out says that the Cloak is more than a merely unfading ordinary invisibility cloak, but grants hiddenness and protection on a deeper level than them. It differs in both quality and quantity, you might say.

One might say the same thing of using or researching dragon blood. And yet...

Everything is toxic in large quantities, and the difficulties & danger of preparation apply to, well, the preparation, not the end product. (This actually makes it an even better potion to make permanent with thestral blood.)
Ah yes. I should have said the most easily noticeable aspect of the cloak. I meant in canon that’s what tipped them off.

You know, it feels significant that Dumbledore loves to experiment with and discover new uses for other species blood, but I’ll be darned if I can figure it out.
Dumbledore is a secret vampire. The reason he couldn’t defeat Grindlewald earlier was because he was flat out unable until he made a bargain with a dark power and gained the strength of Vampirism.

No, the blood sacrifices were made to slake Dumbledore’s vile thirst. After they stopped, well...
