Slow dissolving phosphates do help reduce scale formation..... mainly in things like washing machines and dishwashers.... (ever heard of Calgon)
The problem is to get a reasonable level of protection the dose must be quite high and its effectiveness at preventing scale reduces significantly at boiling point - which is where we need it.
Im not sure Id want to have phosphates in my coffee
. They are fine for reducing the scratchiness of fabrics and getting a gleam on glassware.Phosphate softening products are no longer sold in the US because of the environmental pollution they cause - they also dont like the ion exchange units because of the salt recharge (but at least the salt came from the ocean and is going back there)

.... Sorry if I came across as trying to have a dig at you, I wasnt, just trying to be helpful is all.
