From the Magic of the Caribbean Facebook page, information from a government press conference:
As of October 15, 2022, C-Insurance will be an OPTION and no longer mandatory in order to travel to St. Maarten 🇸🇽 Residents will also no longer be required to test in order to enter the island. EHAS will end in early 2023.l
More Cruise Ship Calls will come to Port St. Maarten. Be ready for High Season!
Actually, that's not the same link. They are a day apart.
The one Carol referred to talked mostly about ending the compulsory Covid-19 insurance and only mentioned that the EHAS requirement was scheduled to end sometime early in 2023. The one posted by @Bahston specifically refers to the proposed end date for the EHAS app being March 2023.
Good news, but unfortunately no help to me for my mid-January trip to the island.
