Yes, taps CAN be drinking water, but not necessarily are.
Don't know if it's an Oz-only thing, but we have some taps (both in parks &
some private properties) that are coloured purple to show that they are connected
to a separate recycled water grid, so the water should NOT be drunk.

Yes, Graeme, in California (USA) we have exactly these (such as my golf course example). While there is no "purple means don't
drink" color-coding here, there seems to be a state law (or something just as firm) that if a publicly-accessible "water
tap" dispenses water which is NOT safe to drink (and again, these are no particular color), there MUST be a sign that says
"non-potable" or "do not drink" or "using reclaimed water" or has the "international red
circle-with-a-slash-means no and a picture of a human drinking water" icon...or ALL of the above.
In California, any pipe or tap carrying recycled water is legally
required to be colored purple. [1] For water from other sources, "Do Not
Drink", "No Beber", or sign PS-013 [2] would be posted. Indoors, the
Uniform Plumbing Code, a national standard, specifies a particular shade
of purple paint for non-potable water pipes when the building also has
potable water pipes. [3]
drinking_water=no is already approved for non-potable water, and there
are non-Boolean values and drinking_water:legal=* if you'd like to split
hairs. I'd expect that a tag for fountains and a tag for drinking
fountains would both imply a default value for drinking_water=* by
default, but the default should be overridden when more is known about
the water source.
With a tag for water taps in general, it isn't as clear. But as a data
consumer or user, I wouldn't be eager to assume that an outdoor tap is
potable without more context. I've been to cemeteries in swampy New
Orleans that have taps signposted "Water for Flowers" and never once
considered that they might be hooked up to the municipal water system
and maintained to the standard of a public drinking fountain.
