Sometimes.  But there may be times when stack files, and the objects 
within them, can provide convenient data storage.  Custom properties are 
a natural fit for server work, but since fields make a convenient way to 
translate some aspects of text-to-HTML and HTML-to-text they can be 
useful too.

I don't use RevServer at the moment, but the following works in the v3.5 
CGI engine, so conceivably it could be made to work with RevServer:


#!../../bin/rev -ui

on startup
   create stack "datastack"
   set the filename of stack "datastack" to "testdata/data.rev"
   set the defaultstack to "datastack"
   create cd
   create field
   save stack "datastack"
   -- Provide some output so we know it completed successfully:
   put "Content-Type: text/html" & crlf &\
            "Content-Length:"&& length("Hello") & crlf & crlf
   put "Done"
   quit
end startup


When I download the created stack, it has both the new card and the 
card's new field.
