Why can't fainted Pokemon be captured in the games?

[Ditto B1tch]

I know the answer is because whittling the Pokemon down adds more difficulty (in a pleasant way) than just knocking them out.

You already have the answer

Knocking them out is easier than letting them with low HP

I mean in Legends Z-A you can now catch fainted Pokemon, or at least after knocking them out you get a few seconds to catch them after defeating them.

I mean in all honesty this and the shiny sound should be in all future main series games but knowing how Gamefreak is they probably intend to keep it unique to the legends games, although I hope I’m wrong.
