Terraform import for AWS provider pass on non-existing resources

When running terraform import on any of the resources below, the command succeeds with Import successful! message even that these resources don’t exist.

resource "aws_s3_bucket" "mybucket" {
  bucket = "none"
}

resource "aws_elasticache_replication_group" "myreplica" {
  replication_group_description = "none"
  replication_group_id = "none"
}

When turning debug log on, it seems the AWS API return 404 but still it doesn’t propagate as failure.
e.g. (same flow happen with S3 import):

Import successful!

Is this expected or something is missing from my side?
The idea for me was to attempt an import and if it fails - create a resource (e.g. create S3 bucket and DynamoDB table before using remote state).
