In my app I used the get_respondent_list API in API v2 to get an overview of the responses and to allow me to select those responses which were relevant to download in greater detail - fields of interest to me included date_modified, status .
I had hoped that /surveys/{ID}/responses would give a similar facility but all it returns for each response is href and id. The parameters of the call enable me to filter the list in various ways but I would need to make several calls to identify the different categories that I am interested in.
When I made a similar point about the survey list it turned out there was an incorrectly documented include parameter which I could use to get additional fields in the response. I tried that for /surveys/{id}/responses but that was rejected. Could such a facility be added?
If not I guess I will go for /surveys/{id}/responses/bulk and do all the work in the app.
