Cache-Control max-age for Shields

I have a question/request regarding badges/shields on Anaconda. Consider the “Number of Downloads” badge for conda-forge::python:

The response is a redirect to shields.io, which then in turn responds with the SVG content along with a HTTP Cache Control header:

Cache-Control: max-age=432000

A duration of 432000 seconds corresponds to 5 days. I’d like my shield to be more up-to-date. I would prefer a maximum age of, say 10 minutes, i.e. 600 seconds.

After reading about similar issues, e.g.

I tried to add the query parameter maxAge=600 to the URL. However, this parameter is dropped when generating the redirect to Shields. I’d like to ask for the redirect to support passing maxAge. Otherwise, please consider passing maxAge with a smaller value to Shields. Thanks!

Here are two recordings of HTTP traffic in HAR format (but using the file extension *.json to circumvent blocking):
