Ran the following scenarios:
Create a new deployment with type recreate:
cf curl "/v3/deployments" -X POST -H "Content-Type: application/json" -d '{ "droplet": { "guid": "73c4ee39-5275-4f61-a935-f89d058fa64c"}, "strategy": "recreate", "relationships": { "app": { "data": { "guid": "a25fa181-7983-4c02-a287-58275952869f" } } } }'
got:
"value":"ACTIVE","reason":"DEPLOYING","details":{"last_successful_healthcheck":"2025-06-12T17:47:35Z","last_status_change":"2025-06-12T17:47:35Z"}},"strategy":"recreate"

cf curl "/v3/deployments?app_guids=a25fa181-7983-4c02-a287-58275952869f"
got
status":{"value":"FINALIZED","reason":"DEPLOYED","details":{"last_successful_healthcheck":"2025-06-12T17:47:50Z","last_status_change":"2025-06-12T17:48:05Z"}},"strategy":"recreate"

Rolled back to a previous droplet using recreate:
cf curl "/v3/deployments" -X POST -H "Content-Type: application/json" -d '{ "droplet": { "guid": "7c0fab37-e72e-4d2f-aa92-a3e1152e11f3"}, "strategy": "recreate", "relationships": { "app": { "data": { "guid": "a25fa181-7983-4c02-a287-58275952869f" } } } }'
got
status":{"value":"ACTIVE","reason":"DEPLOYING","details":{"last_successful_healthcheck":"2025-06-12T17:52:56Z","last_status_change":"2025-06-12T17:52:56Z"}},"strategy":"recreate"

Tried recreate with max-in-flight
cf curl "/v3/deployments" -X POST -H "Content-Type: application/json" -d '{ "droplet": { "guid": "7c0fab37-e72e-4d2f-aa92-a3e1152e11f3"}, "strategy": "recreate", "options": { "max_in_flight": 2 }, "relationships": { "app": { "data": { "guid": "a25fa181-7983-4c02-a287-58275952869f" } } } }'
{"errors":[{"detail":"Options max in flight is not a supported option for recreate deployment strategy","title":"CF-UnprocessableEntity","code":10008}]}

Tried recreate with canary steps
cf curl "/v3/deployments" -X POST -H "Content-Type: application/json" -d '{ "droplet": { "guid": "7c0fab37-e72e-4d2f-aa92-a3e1152e11f3"}, "strategy": "recreate", "options": { "canary": { "steps": [ { "instance_weight": 10 } ] } }, "relationships": { "app": { "data": { "guid": "a25fa181-7983-4c02-a287-58275952869f" } } } }'
{"errors":[{"detail":"Options canary are only valid for Canary deployments","title":"CF-UnprocessableEntity","code":10008}]}
