features_v2.json: .updated.when is not accurate.

[ArthurSonzogni]

I am fetching updates to ChromeStatus every day. It starts with fetching a summary of every features (~2700 features) from a single response: https://chromestatus.com/features_v2.json

Then I am making subsequent requests to 1-3 URLs below:

• https://chromestatus.com/api/v0/features/${features[i].id}
• https://chromestatus.com/api/v0/features/${features[i].id}/gates
• https://chromestatus.com/api/v0/features/${features[i].id}/progress

To avoid making up to 3x2700 requests every day, I am only considering the ones updated recently. I am using features[i].updated.when from the features_v2.json.

I recently discovered the features[i].updated.when is not updated when the feature owner request a review, or add comments. See this feature.

Do you consider this behavior to be a bug?
If not, is there any other API that would be a better fit?
