The thing is that it is not necessary to use a mode directive. Either 
the user might be happy with the default mode FPC and just add some 
modeswitch for extended functionality or the mode might be provided as a 
command line parameter again with adding some special functionality.

And it would be much more effort to keep track of when a modeswitch 
directive was used in case a mode directive is used later on. Just not 
worth the effort as it's documented that a mode directive resets any 
modeswitches.
