the Olympics is adapting with time(Transgender athletes inclusion etc) which is why they could come up with the West Indies problem that you pointed out since that country provides a shitton of entertainment in the T20 format.
West Indies being a country into Olympics completely unfair thing because they are participating in this event with different flags which is nothing new and most chances Olympics committee will never allow them to have spot here with this name they all needed to be had their separate teams which could be better. England is also competing in this with different flags which is good for them so here having West Indies is not good to deal all teams needed to be had qualifiers and then top six teams could be into this event for Gold medal game.
Currently, Australia, India and New Zealand are best teams in shorter format I am expecting them to fight for top spots others are having nothing better chance but on their day Proteas and England can also do good, but Pakistan is having no chance for anything good.
