What's with the new fashion of Alpha, Beta and Omega bloods?

I have noticed, that there are more than one mangaka, who does these stories (Thought i cannot remember their names)

Is this some new invention in yaoi mangas?

And cause i have totally forgotten the mangas, than what were the mangas those are used in?

One is Paradigm Shift (just reading it) (https://www.mangaupdates.com/series.html?id=126176)

The Omegaverse trope itself isn't something new. It has been used in fanfictions for quite a while now although I think some mangakas just recently started to incorporate it into their works.
(It certainly isn't a yaoi invention)
Here are some Omegaverse manga:
Abarenbo Honey
Pendulum: Kemonohito Omegabirth
Romantic Joutou
Sayonara Koibito, Mata Kite Tomodachi
Oyasuminasai No Ato Wa
Boku no high spec kareshi-sama
Tadaima, okaeri
Junjou shounen
Hebi no seikatsu
And a whole lot of Attack on Titan doujinshi, particularly Eren x Levi (or Levi x Eren) ones

Bokura ga Tsugai ni Naru Made this manga I like the most if its about omega and alpha hihihi....
