Alchemical items and bonus types?

[Selkor]

I was thinking about alchemists and the items they make, why do they have an Item bonus? It seems like that would create a lot of conflict with items that other characters are using? Beyond having another bonus type, is there a reason to not make Alchemical items have an "Alchemical Bonus" instead of an "Item Bonus"? Just curious from those that have played or who are better theorycrafters than I. Any insights would be appreciated, as my group had to delay our start of the playtest due to scheduling and I wanted to play an alchemist.

I don't know of a reason not to.
I do know that plenty of situation where an item has less of an effect or no effect because a magical item gives the same bonus.

I think it would be more effecient/feel better if they were alchemical bonuses
