Yes, exactly.

Certainly g_irepository_get_info doesn't return a type info that 
represents an alias type declared in a namespace.  It's not clear to me 
how g_base_info_get_attribute could be used for alias information.  We 
would have to check an attribute of anything with a type, e.g. 
arguments, return values, properties?  Also, I can't see any 
documentation about such an attribute.
