SC 1.4.4: browser zoom and responsive design

With interest I have followed the discussion about SC 1.4.4, resize text. Conclusion: browser zoom is allowed.

My question is about browser zoom and responsive design.

Suppose I visit a website. It is a garbage-day calender. It gives me the option to browse through the months to check when my garbage is collected. After a few zooms the responsive design kicks in. In this design the calender is replaced by a static list without the option to browse through the months. In other words: the responsive design does not give me the same options as the desktop design does.

https://www.w3.org/TR/2016/NOTE-WCAG20-TECHS-20161007/G142 says under Tests > procedure:

1. Display content in a user agent

2. Zoom content to 200%

3. Check whether all content and functionality is available

The responsive design in my example misses functionality that the desktop design does have.

Is this a violation of SC 1.4.4?
