API: Include marker attributes in search results?

I wanted to use the API to add a way of browsing artworks in a city by date (and to spot anything that’s currently missing that, or has an implausible value). But currently the attributes of an artwork aren’t returned from the search results: only from /api/markers/{markerId}

This means I need to hit that API call once per artwork in a location, which is obviously doable, but presumably not great for the server, even if I cache the results and only refetch if lastUpdated changes. I’m guessing the search API omits these largely just to avoid transferring lots of extra unnecessary data in the default case? If so perhaps there could be an extra query parameter to include them in the results?
