We recently published an extension to Visual Studio Marketplace and attempted to embed a status badge in one of our README files, but it was rejected explicitly by VSM due to an unauthorized status badge:
Your reference to the SVG image ‘<badge url>’ is not supported. Please see https://aka.ms/vsmarketplace_badge for more details.
I was surprised to not see CircleCI on the
list of supported badges, it'd be great if you were.
