:::::Yes my suggestion is to be inclusive. Include subjects such as cosmology with appropriate nuance if there is a reliable source. I know some may say that rather takes the sting out of calling really really PS subjects pseudoscience, but this is Wikipedia, and we are not here to slag stuff off.  Equally, if there is a real PS issue in a subject, even if GPs use the umbrella subject, then it can be mentioned. Why am I saying all this? Because it complies with NPOV on inclusion of all relevant views. Its pretty simple guys, we should all understand NPOV policy pretty well by now.
