I expect so. AA, for example, has said that after 3/16, they will have no service to SXM through May 6. Given that they operated a flight today, and that this list includes flights through March 22, it suggests to me that these may be repatriation flights - operating primarily to get people home, not to bring new people in. I note that SXM currently has a ban on passengers, other than Sint Maarten residents, who have been in the US within the past 21 days,.
