Drive API bug: no 404 response on drive.children.list/drive.files.list

I realise this is not a bug directly with the Obj-c client itself and the 
server API but I cannot find a better place to report this.

What steps will reproduce the problem?
1. Create folder with files
2. Permanently delete folder with files
3. Perform drive.children.list or drive.files.list q:id in parents

What is the expected output? What do you see instead?
Expected output should be a 404 error, and was until last week

instead received, note the missing results collection:
The library interprets this as 0 children

id = "gtl_19";
result =     {
    etag = "\"maCRbN5nR56FjQPLihEiz9nzpho/vyGp6PvFo4RvsFtPoIWeCReyIC8\"";
    kind = "drive#childList";
};

What version of the product are you using? On what operating system?
OSX/iOS

Please provide any additional information below.
This is new behaviour as until recently my tests successfully forced a 404 
error whereas now they fail with 0 results.
