I don't see why. Most of the code using DOM bindings simply ignores the
errors, and existing code is not going to change. I don't see any major
usability issue, neither any regression at all. Is it really a major
usability going from:

GError *error = NULL;
webkit_dom_foo_do_bar (foo, &error);
if (error) {
    g_error_free (error);


webkit_dom_foo_do_bar (foo);
error = webkit_dom_foo_get_error (foo);
if (error)

It even has advantages, for example if you are not interested in the
error details you can null-check the return value of get_error()
without having to worry about freeing the GError. 

I agree this is not ideal for a GObject API, but I really don't see how
this is a major problem, to be honest.
