Inconsistency in returned json for chained get and chained create

I noticed something strange about the JSON that API calls return.

Suppose I want to get a contact and its websites, using chaining. This is the request I use:

/dev1/sites/all/modules/civicrm/extern/rest.php?entity=Contact&action=get&json={"sequential":1,"id":9076,"api.Website.get":{}}&api_key=yoursitekey&key=yourkey

Here is the result:

{
"is_error":0,
"version":3,
"count":1,
"id":9076,
"values":[{
"contact_id":"9076",
"contact_type":"Individual",
// ...
"api.Website.get":{
"is_error":0,
"version":3,
"count":2,
"values":[

{ "id":"59", "contact_id":"9076", "url":"http:\/\/example.com" }

,

{ "id":"60", "contact_id":"9076", "url":"http:\/\/example.org" }

]
}
}]
}

Now if I create a new contact, and I provide websites using a chained create action like this:

/dev1/sites/all/modules/civicrm/extern/rest.php?entity=Contact&action=create&sequential=1&json={"last_name":"Smith","contact_type":"Individual","api.Website.create":[

{"url":"http://smith.org"}

,

{"url":"http://smath.org"}

]}&api_key=yoursitekey&key=yourkey

This is the result I get:

{
"is_error":0,
"version":3,
"count":1,
"id":9077,
"values":{
"0":{
"id":"9077",
"contact_type":"Individual",
// ...
"9077":{
"api.Website.create":[{
"is_error":0,
"version":3,
"count":1,
"id":61,
"values":[

{ "id":"61", "contact_id":"9077", "url":"http:\/\/smith.org", "website_type_id":"" }

]
},
{
"is_error":0,
"version":3,
"count":1,
"id":62,
"values":[

{ "id":"62", "contact_id":"9077", "url":"http:\/\/smath.org", "website_type_id":"" }

]
}]
}
}
}

So there are some extra indices ("0") and Id's ("9077"), which makes the parsing of the json harder (for me at least ). It appears to me that 'sequential=1' is ignored.

I think the correct result would be:

{
"is_error":0,
"version":3,
"count":1,
"id":9077,
"values":[{
"id":"9077",
"contact_type":"Individual",
// ...
"api.Website.create":{
"is_error":0,
"version":3,
"count":2,
"id":61,
"values":[

{ "id":"61", "contact_id":"9077", "url":"http:\/\/smith.org", "website_type_id":"" }

,

{ "id":"62", "contact_id":"9077", "url":"http:\/\/smath.org", "website_type_id":"" }

]
}
}]
}
