Yes. Since we've gone this far, how about the facility to specify
a final size after the best size is known so that an application
might have something like:

GtkIconInfo *info = gtk_icon_theme_lookup_icon (theme, name, size, 0);
if (gtk_icon_info_get_base_size(icon) < size &&
  gtk_icon_info_get_base_size(icon) > size - 2)
	gtk_icon_info_set_size(icon, gtk_icon_info_get_base_size());
GdkPixbuf *pixbuf = gtk_icon_info_load_icon (info);
gdk_icon_info_free (info);

if it wanted to determine its own rules for when scaling should be
applied, or would that simply contribute to unwanted application
divergence?
