Actually I did mention that months ago in another thread. Someone told me I was stupid for paying even more money just to avaoid epic to which I replied that I had no problem with paying iO even more for Hitman really is worth it. I mean yes, epic may have a bigger cut than Stadia, but epic / 3 is less money than full trilogy / Stadia.
When we launched HITMAN on Stadia, we included platform exclusive items that were unlocked by playing each game from the World of Assassination trilogy; The Sunset Rubber Duck, Orange Pinstripe Briefcase and White Sunset Suit.
Due to how these items were distributed to Stadia players, they will not be part of the Stadia Progression Carryover. However, we are committed to making all of these items available to all HITMAN 3 players on all platforms in a future patch.
