Agreed, but it still feels weird.
I’d like to add that I expect the games to, much like previous games (LGPE included), still have all data for the cut Pokemon, Mega Stones, Z-Crystals, and items in them that aren’t otherwise available, because Game Freak likes to copy+Paste their code throughout the entries. Let’s see if datamining proves me theory correct.
Edit: Forgot to mention, Japan only just found out that Pokemon were being cut through leaks. GameFreak didn’t even tell them.
