Yes, and thanks for setting up this nice eye candy.

Only minor issue is that the new badges don't play well with hosting
services that aggressively cache images, such as GitHub:

  https://github.com/magnars/dash.el

Note that the GNU-devel ELPA version trails the corresponding MELPA one
due to server-side caching.

MELPA seems to solve this by configuring their NGINX web server to serve
badges with the HTTP header 'Cache-Control: no-cache':

Is there someone here with access to GNU ELPA's Apache configuration
that would make a similar change?  If not, where should this request go?

Thanks,
