[Tagging] building typology vs usage

I certainly recall reading about this in the wiki, but I agree that in
common use, the building=* tag appears to be used mostly for the
current function, rather than specifying a certain form.
The most common values of building= are:
0) yes (non-specific)
1) =house - both a structural form and a function (residential)
2) =residential - function, not really a specific form of building
3) =garage - function and form
4) =apartments - function (multi-family residential)
5) =detacted - synonym for house but more specific
6) =hut - form of construction (crude/simple)
7) =industrial - function
8) =shed - form but also function ("used as storage or workshop")
9) =roof - form
10) =terrace - form but also function (residential)
11) =school - function mainly
12) =garages - form and function
13) =construction - lifecycle state
14) =retail - mainly function, because the form of retail buildings varies
15) =greenhouse - form = function here
16) =barn - form=function
17) =farm_auxiliary - function (no particular form, and this is only
the general function)
18) =church - claimed to be a form?
19) =warehouse - function (but usually has the same general form)
20) =service - function
Often the "form follows function" as they say, but it looks like
tagging the function of a building is as common as tagging the form.
