Centring on GMT is conventional and probably makes more sense than anywhere else. Australians may beg to differ though:

(I quite like that map, actually.)

I love it as well so interesting to see the world 'upside down',ales everything so unrecognisable.

But GMT is still Eurocentric and unimportant from the perspective of an individual looking at a map, I do wonder if that will ever change?

It still dilates the northern hemisphere and squashes the southern hemisphere though.
