I think this way it communicate better to the player which items are fused. Imagine to remember thousand of variations a shield have to just know which one has the effect of which item.
Item descriptions are a thing tho, you can also have icons to illustrate what effects the item currently holds.
I'm just disappointed to wait so long on a delayed game and then see something that, imo, looks jank. I'm sure I'll still have fun but it's such a weird decision.
