Shipping Safari has a very limited form of the File API, so I'd prefer  
a plan where we do not regress the already shipped capability. That  
could mean either multiple flags for different subfeatures, or making  
sure to implement back ends for the mac and win ports when landing any  
new features. Maintainers of other ports may have similar concerns,  
but I cannot say offhand what has already shipped in other ports.

Incidentally, some but not all porting macros are defined here: <http://trac.webkit.org/wiki/Porting%20Macros%20plan

revising some of the macros) but if anyone would like to help document  
macros in use at the end, that would be great.
