G_PARAM_CONSTRUCT cause to explicitly initialize the property during object construction. This is an unnecessary overhead that we can easily avoid. The overhead is because G_PARAM_CONSTRUCT parameters are always set with g_object_set() before calling constructed(). Even if they are not specified during g_object_new(), in which case it calls set with the property's default value. This also requires g_object_new() to iterate all properties to find and sort the construct properties. NMSetting are supposed to be simple classes. They don't need to have their properties initialized before object construction completes. Especially if the default values are NULL or zero, in which case there is nothing to do. If the default value is not NULL or zero, we need to initialize the field instead in the nm_setting*_init() function.
