Nice to see something being written about it, at least!
Just a small point - Curaçao, Aruba and Bonaire are largely Papiamento-speaking (rather than Dutch-speaking). Perhaps "Dutch-influenced" would be better.
Also, Bonaire is not yet a member of CONCACAF (it's a member of CFU, after a period of being a provisional member, and is as yet simply an associate member of CONCACAF). Not sure how long it must remain an associate, but Guadeloupe, Martinique et al. were associate members for quite some time before they were accepted as full members recently.
