If you search on the wiki for 'public building' you get 
amenity=public_building ... I think it should suggest building=public as 
the first preference.

Probably more than one value!

In some parts of the world .. 'public buildings' do have an 
'architectural style'.

The requirements of the building occupiers do result in set 
relationships between form (how it looks) and function (what it gets 
used for).
However that are exceptions - a corner store can be used as a residence, 
resulting in building=retail, landuse=residential. Despite the 
occasional 'customer' entering the bedroom for a loaf of bread.

building=public allows for those buildings that have some architectural 
style that says 'public building'.
amenity=public_building conveys ???? Here is a building .. that is 
public .. but the function (amenity) is unknown? So why not use the 
clearer building=public? 'We' may prefer more specific tagging .. but in 
some places that may not be possible. And those that want to tag more 
information will then be looking elsewhere as to what they want to tag 
... amenity=toilets for instance. Or amenity=shelter.
