You're right and the command was added *for* the simplefonts module :)

There is a command to check the context version

%D \macros
%D   {doifolderversionelse}
%D We start with a macro specially for Aditya who wants to be able
%D to use development versions of \MKIV\ for real documents.
%D \starttyping
%D \doifolderversionelse\contextversion{2001.02.03}{yes}{no}
%D \doifolderversionelse\contextversion{3001.02.03}{yes}{no}
%D \stoptyping

and end the module and output a message in the terminal but then you  
you will get a error message in the document itself because a few  
(e.g. \setmainfont) are no longer defined.
