South Africa doesn't have the same cultural connectivity to the United Kingdom that Canada, Australia and New Zealand do. There's also no 'big bad' for South Africa, whereas with Canada there is the United States, and with Australia and New Zealand there is the East Asian blob.

This isn't about maximizing the power or extent of the UK, it's about what makes the most sense.

I just thought that they had some kind of cultural connection since United Kingdoms did expand down there. I guess that I was wrong. Oh well.
