Yes perfectly fine.
Never thought of it as immature but I suppose..... I see it as a kids drink just because I haven't drunk it since I was a kid. I didn't drink the preferable fizzy drinks as a kid, but I occasionally drink coke/Fanta or juice (also not an 'adult' drink and would be considered more immature by the same logic) now.
I suppose if there is an immature angle; is the reason parents give kids squash so they actually drink water? When we drink coke/ fanta it's not for hydration, we know it's not good for us we do so for mouth pleasure / a treat. I drink water without dilution, I suppose if adults are needing to self parent to hydrate themselves by flavouring water then.......maybe?
But really doesn't matter, better than not drinking water. Enjoy

I refuse to be told what to do by some jumped up advert.
Except maybe Robinsons / squash adverts
Edit. Also I drink herbal and green tea which is a gateway drug to fruit tea which is like warm blackcurrant which I enjoy but is the lowest of the low. So no judgement
