Dripstone Drips are Water for Purple Soda

[TheRexYo]

I don't know if this is intended or not, but if you use pointed dripstone below a Purple Soda puddle, the particles are water droplets and as far as I can tell they don't renew cauldrons either. I was hoping this would be a thing for the sake of renewability, but it's understandable if that's not a worthwhile feature.
