Just to make sure I’m not missing something – these are dropped because the on*Complete functions are not called in the case of errors anymore, right?

I'm also curious about it. Is that why the search setter doesn't need to have onParseError in this case?

Yes, the completion and the errors are handled in different callbacks, since it doesn't really make sense to pass all these parsed parts to an error callback anyway.

The setters are ignoring errors per the spec at the moment, so they don't have error callbacks.
