It's a drug. The manufacturer may mutter excuses about "flavor", but only because they know it's not socially acceptable to sell it as a drug.
I use it as a drug. This means I want to know about how much I'm getting, which in turn means I don't want it slipped into things I don't expect to have it. Nor do I want to be served decaf tea without being told it's decaf: same principle.
Considering how many companies will trumpet "New packaging!" on an unchanged product, I don't understand why the root beer maker didn't take the opportunity to put "New and improved!" on this if they think that adding caffeine is an improvement.
