The systems thinking in respect of how the building skin interfaces with 
water has changed with the development of materials and building technology.
Glass in particular, most panel systems, including granite sheets, are 
generally less pervious to water and therefore require less protection 
than brick, limestone or TC w/ mortar joints.
Improvements in sealant technology. Fewer nooks & crannies etc. make it 
that water flows more evenly in sheets and not in patterns that 
concentrate water flow in funnel streams.
The whole difference of curtain wall construction.
The protection moved from the cornice into the fabric of the field of 
the elevation.
The form follows function aesthetic (in my estimation largely abandoned 
with all of the unmaintainable twisty glass buildings being built 
currently).
If a cornice is not needed then why be retro?
