How to create a private system entity from cloud code?

[Carlos Barcenilla]

I want to create a private system entity. I can do it using the portal with "ACL: Private".

However, from Cloud Code (S2S) I cannot manage to do it:

This creates a public system entity:
createSystemEntity(entityType, timeToLive, null, data)

This raises an error:
createSystemEntity(entityType, timeToLive, { "other": 0 }, data)

{
"reason_code": 40564,
"status_message": "Processing exception: ACL must be readable",
"status": 400
}

This workaround does the job in two API calls:
createSystemEntity(entityType, timeToLive, { "other": 1 }, data) -> creates a public system entity
updateSystemEntityAcl(createResult.data.entityId, -1, { other: 0 }) -> makes the entity private

If I can update the entity to make it private I should be able to create it as private.

Is there a way to do do it in the creation call?

Tnx
