It means I may except this feature will be included, too:

The check is performed at compile time by gengetopt while the others at runtime 
by the generated source. This way a default group option (groupdefault?) will 
behave exactly the same as if it were specified by the user at commandline. Am 
I right? 

Btw, default group option resembles to "flag on" a little bit however makes 
much more sense because to make default one of option from a mutually exlcusive 
group makes sense ;)

I remember now that some gengetopt users were asking in the list how to deal 
with more than one .ggo files each one defining options of different 
"subcommands" to the application. If default group option (groupdefault in 
short) was implemented such subcommands (with their multiple .ggo files) may be 
converted into a single .ggo file. Not always but sometimes it can be very 
handy...
